In articulatory phonetics , a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract , except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are [p] and [b], pronounced with the lips ; [t] and [d], pronounced with the front of the tongue ; [k] and [g], pronounced with the back of the tongue; [h] , pronounced throughout the vocal tract; [f] , [v], and [s] , pronounced by forcing air through a narrow channel ( fricatives ); and [m] and [n] , which have air flowing through the nose ( nasals ). Most consonants are pulmonic , using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of ejectives , implosives , and clicks . Contrasting with consonants are vowels .

145-632: Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet , linguists have devised systems such as the International Phonetic Alphabet (IPA) to assign a unique and unambiguous symbol to each attested consonant. The English alphabet has fewer consonant letters than the English language has consonant sounds, so digraphs like ⟨ch⟩ , ⟨sh⟩ , ⟨th⟩ , and ⟨ng⟩ are used to extend

290-719: A is not written, as in the Indic abugidas, The source of the term "abugida", namely the Ge'ez abugida now used for Amharic and Tigrinya , has assimilated into their consonant modifications. It is no longer systematic and must be learned as a syllabary rather than as a segmental script. Even more extreme, the Pahlavi abjad eventually became logographic . Thus the primary categorisation of alphabets reflects how they treat vowels. For tonal languages , further classification can be based on their treatment of tone. Though names do not yet exist to distinguish

435-418: A syllable : The most sonorous part of the syllable (that is, the part that is easiest to sing), called the syllabic peak or nucleus , is typically a vowel, while the less sonorous margins (called the onset and coda ) are typically consonants. Such syllables may be abbreviated CV, V, and CVC, where C stands for consonant and V stands for vowel. This can be argued to be the only pattern found in most of

580-559: A combination of these features, such as "voiceless alveolar stop" [t] . In this case, the airstream mechanism is omitted. Some pairs of consonants like p::b , t::d are sometimes called fortis and lenis , but this is a phonological rather than phonetic distinction. Consonants are scheduled by their features in a number of IPA charts: Symbols to the right in a cell are voiced , to the left are voiceless . Shaded areas denote articulations judged impossible. The recently extinct Ubykh language had only 2 or 3 vowels but 84 consonants;

725-416: A consistent one-to-one correspondence between the letters and the phonemes so that a writer could predict the spelling of a word given its pronunciation, and a speaker would always know the pronunciation of a word given its spelling, and vice versa. However, this ideal is usually never achieved in practice. Languages can come close to it, such as Spanish and Finnish . Others, such as English, deviate from it to

870-523: A consonant that is very similar. For instance, an areal feature of the Pacific Northwest coast is that historical *k has become palatalized in many languages, so that Saanich for example has /tʃ/ and /kʷ/ but no plain /k/ ; similarly, historical *k in the Northwest Caucasian languages became palatalized to /kʲ/ in extinct Ubykh and to /tʃ/ in most Circassian dialects. Symbols to

1015-469: A consonant, with diacritics for disambiguation. In the Pollard script , an abugida, vowels are indicated by diacritics. The placing of the diacritic relative to the consonant is modified to indicate the tone. More rarely, a script may have separate letters for tones, as is the case for Hmong and Zhuang . For many, regardless of whether letters or diacritics get used, the most common tone is not marked, just as

1160-499: A determination, and simply assign the flap in both cases to a single archiphoneme, written (for example) //D// . Further mergers in English are plosives after /s/ , where /p, t, k/ conflate with /b, d, ɡ/ , as suggested by the alternative spellings sketti and sghetti . That is, there is no particular reason to transcribe spin as /ˈspɪn/ rather than as /ˈsbɪn/ , other than its historical development, and it might be less ambiguously transcribed //ˈsBɪn// . A morphophoneme

1305-462: A given language may be highly distorted; this is the case with English, for example. The correspondence between symbols and phonemes in alphabetic writing systems is not necessarily a one-to-one correspondence . A phoneme might be represented by a combination of two or more letters ( digraph , trigraph , etc. ), like ⟨sh⟩ in English or ⟨sch⟩ in German (both representing

1450-466: A given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables , while logographies assign symbols to words , morphemes , or other semantic units. The first letters were invented in Ancient Egypt to serve as an aid in writing Egyptian hieroglyphs ; these are referred to as Egyptian uniliteral signs by lexicographers . This system

1595-411: A large number of loanwords at different times, retaining their original spelling at varying levels. However, even English has general, albeit complex, rules that predict pronunciation from spelling. Rules like this are usually successful. However, rules to predict spelling from pronunciation have a higher failure rate. Sometimes, countries have the written language undergo a spelling reform to realign

1740-476: A letter for /ti/ . Devanagari is typically an abugida augmented with dedicated letters for initial vowels, though some traditions use अ as a zero consonant as the graphic base for such vowels. The boundaries between the three types of segmental scripts are not always clear-cut. For example, Sorani Kurdish is written in the Arabic script , which, when used for other languages, is an abjad. In Kurdish , writing

1885-451: A much larger degree. The pronunciation of a language often evolves independently of its writing system. Writing systems have been borrowed for languages the orthography was not initially made to use. The degree to which letters of an alphabet correspond to phonemes of a language varies. Languages may fail to achieve a one-to-one correspondence between letters and sounds in any of several ways: National languages sometimes elect to address

2030-406: A near minimal pair. The reason why this is still acceptable proof of phonemehood is that there is nothing about the additional difference (/r/ vs. /l/) that can be expected to somehow condition a voicing difference for a single underlying postalveolar fricative. One can, however, find true minimal pairs for /ʃ/ and /ʒ/ if less common words are considered. For example, ' Confucian ' and 'confusion' are

2175-456: A phenomenon where letters have been given names distinct from their pronunciations. Systems with acrophony include Greek, Arabic , Hebrew , and Syriac ; systems without include the Latin alphabet . More recently however, four cylinder seals dating to 2400 BC and found at the site of Umm el-Marra , in present-day Syria , are incised with what is potentially the earliest known alphabetic writings in

2320-483: A phoneme has more than one allophone , the one actually heard at a given occurrence of that phoneme may be dependent on the phonetic environment (surrounding sounds). Allophones that normally cannot appear in the same environment are said to be in complementary distribution . In other cases, the choice of allophone may be dependent on the individual speaker or other unpredictable factors. Such allophones are said to be in free variation , but allophones are still selected in

2465-401: A set (or equivalence class ) of spoken sound variations that are nevertheless perceived as a single basic unit of sound by the ordinary native speakers of a given language. While phonemes are considered an abstract underlying representation for sound segments within words, the corresponding phonetic realizations of those phonemes—each phoneme with its various allophones—constitute

2610-417: A set of phonemes, and these different systems or solutions are not simply correct or incorrect, but may be regarded only as being good or bad for various purposes". The linguist F. W. Householder referred to this argument within linguistics as "God's Truth" (i.e. the stance that a given language has an intrinsic structure to be discovered) vs. "hocus-pocus" (i.e. the stance that any proposed, coherent structure

2755-409: A set of some 24 hieroglyphs that are called uniliterals, which are glyphs that provide one sound. These glyphs were used as pronunciation guides for logograms , to write grammatical inflections, and, later, to transcribe loan words and foreign names. The script was used a fair amount in the 4th century CE. However, after pagan temples were closed down, it was forgotten in the 5th century until

2900-456: A simple /k/ , colloquial Samoan lacks /t/ and /n/ , while Rotokas and Quileute lack /m/ and /n/ . During the development of phoneme theory in the mid-20th century, phonologists were concerned not only with the procedures and principles involved in producing a phonemic analysis of the sounds of a given language, but also with the reality or uniqueness of the phonemic solution. These were central concerns of phonology . Some writers took

3045-435: A single morphophoneme, which might be transcribed (for example) //z// or |z| , and which is realized phonemically as /s/ after most voiceless consonants (as in cat s ) and as /z/ in other cases (as in dog s ). All known languages use only a small subset of the many possible sounds that the human speech organs can produce, and, because of allophony , the number of distinct phonemes will generally be smaller than

3190-512: A single phoneme: the one traditionally represented in the IPA as /t/ . For computer-typing purposes, systems such as X-SAMPA exist to represent IPA symbols using only ASCII characters. However, descriptions of particular languages may use different conventional symbols to represent the phonemes of those languages. For languages whose writing systems employ the phonemic principle , ordinary letters may be used to denote phonemes, although this approach

3335-411: A speaker pronounces /p/ are phonetic and written between brackets, like [p] for the p in spit versus [pʰ] for the p in pit , which in English is an aspirated allophone of /p/ (i.e., pronounced with an extra burst of air). There are many views as to exactly what phonemes are and how a given language should be analyzed in phonemic terms. Generally, a phoneme is regarded as an abstraction of

3480-542: A specific phonetic context, not the other way around. The term phonème (from Ancient Greek : φώνημα , romanized :  phōnēma , "sound made, utterance, thing spoken, speech, language" ) was reportedly first used by A. Dufriche-Desgenettes in 1873, but it referred only to a speech sound. The term phoneme as an abstraction was developed by the Polish linguist Jan Baudouin de Courtenay and his student Mikołaj Kruszewski during 1875–1895. The term used by these two

3625-453: A syllabary, as their name would imply, because each glyph stands for a consonant and is modified by rotation to represent the following vowel. In a true syllabary, each consonant-vowel combination gets represented by a separate glyph. All three types may be augmented with syllabic glyphs. Ugaritic , for example, is essentially an abjad but has syllabic letters for /ʔa, ʔi, ʔu/ These are the only times that vowels are indicated. Coptic has

3770-778: A systematic graphic modification of the consonants. The earliest known alphabet using this sense is the Wadi el-Hol script , believed to be an abjad. Its successor, Phoenician , is the ancestor of modern alphabets, including Arabic , Greek , Latin (via the Old Italic alphabet ), Cyrillic (via the Greek alphabet), and Hebrew (via Aramaic ). Examples of present-day abjads are the Arabic and Hebrew scripts ; true alphabets include Latin , Cyrillic, and Korean hangul; and abugidas, used to write Tigrinya , Amharic , Hindi , and Thai . The Canadian Aboriginal syllabics are also an abugida, rather than

3915-600: A unique order based on phonology : The letters are arranged according to how and where the sounds get produced in the mouth. This organization is present in Southeast Asia, Tibet, Korean hangul , and even Japanese kana , which is not an alphabet. In Phoenician, each letter got associated with a word that begins with that sound. This is called acrophony and is continuously used to varying degrees in Samaritan , Aramaic , Syriac , Hebrew , Greek , and Arabic . Acrophony

4060-467: A unique phoneme in such cases, since to do so would mean providing redundant or even arbitrary information – instead they use the technique of underspecification . An archiphoneme is an object sometimes used to represent an underspecified phoneme. An example of neutralization is provided by the Russian vowels /a/ and /o/ . These phonemes are contrasting in stressed syllables, but in unstressed syllables

4205-452: A valid minimal pair. Besides segmental phonemes such as vowels and consonants, there are also suprasegmental features of pronunciation (such as tone and stress , syllable boundaries and other forms of juncture , nasalization and vowel harmony ), which, in many languages, change the meaning of words and so are phonemic. Phonemic stress is encountered in languages such as English. For example, there are two words spelled invite , one

4350-401: A vowel. The word consonant may be used ambiguously for both speech sounds and the letters of the alphabet used to write them. In English, these letters are B , C , D , F , G , J , K , L , M , N , P , Q , S , T , V , X , Z and often H , R , W , Y . In English orthography , the letters H, R, W, Y and the digraph GH are used for both consonants and vowels. For instance,

4495-464: A vowel. He divides them into two subcategories: hēmíphōna ( ἡμίφωνα 'half-sounded'), which are the continuants , and áphōna ( ἄφωνος 'unsounded'), which correspond to plosives . This description does not apply to some languages, such as the Salishan languages , in which plosives may occur without vowels (see Nuxalk ), and the modern concept of "consonant" does not require co-occurrence with

4640-465: Is Elder Futhark , believed to have evolved out of one of the Old Italic alphabets . Elder Futhark gave rise to other alphabets known collectively as the Runic alphabets . The Runic alphabets were used for Germanic languages from 100 CE to the late Middle Ages, being engraved on stone and jewelry, although inscriptions found on bone and wood occasionally appear. These alphabets have since been replaced with

4785-431: Is a (perhaps allophonic) difference in articulation between these segments, with the [j] in [ˈjɛs] yes and [ˈjiʲld] yield and the [w] of [ˈwuʷd] wooed having more constriction and a more definite place of articulation than the [ɪ] in [ˈbɔɪ̯l] boil or [ˈbɪt] bit or the [ʊ] of [ˈfʊt] foot . The other problematic area is that of syllabic consonants, segments articulated as consonants but occupying

4930-418: Is a purely articulatory system apart from the use of the acoustic term 'sibilant'. In the description of some languages, the term chroneme has been used to indicate contrastive length or duration of phonemes. In languages in which tones are phonemic, the tone phonemes may be called tonemes . Though not all scholars working on such languages use these terms, they are by no means obsolete. By analogy with

5075-414: Is a theoretical unit at a deeper level of abstraction than traditional phonemes, and is taken to be a unit from which morphemes are built up. A morphophoneme within a morpheme can be expressed in different ways in different allomorphs of that morpheme (according to morphophonological rules). For example, the English plural morpheme -s appearing in words such as cats and dogs can be considered to be

5220-439: Is a verb and is stressed on the second syllable, the other is a noun and stressed on the first syllable (without changing any of the individual sounds). The position of the stress distinguishes the words and so a full phonemic specification would include indication of the position of the stress: /ɪnˈvaɪt/ for the verb, /ˈɪnvaɪt/ for the noun. In other languages, such as French , word stress cannot have this function (its position

5365-509: Is an inscription on the sarcophagus of King Ahiram c.  1000 BCE . This script is the parent script of all western alphabets. By the 10th century BCE, two other forms distinguish themselves, Canaanite and Aramaic . The Aramaic gave rise to the Hebrew alphabet . The South Arabian alphabet , a sister script to the Phoenician alphabet, is the script from which the Ge'ez abugida

5510-417: Is any set of similar speech sounds that is perceptually regarded by the speakers of a language as a single basic sound—a smallest possible phonetic unit—that helps distinguish one word from another. All languages contains phonemes (or the spatial-gestural equivalent in sign languages ), and all spoken languages include both consonant and vowel phonemes. Phonemes are primarily studied under

5655-641: Is as good as any other). Different analyses of the English vowel system may be used to illustrate this. The article English phonology states that "English has a particularly large number of vowel phonemes" and that "there are 20 vowel phonemes in Received Pronunciation, 14–16 in General American and 20–21 in Australian English". Although these figures are often quoted as fact, they actually reflect just one of many possible analyses, and later in

They feature many letters that appear to have been borrowed from or influenced by Greek and Hebrew. Many phonetic scripts exist in Asia. The Arabic alphabet , Hebrew alphabet , Syriac alphabet , and other abjads of the Middle East are developments of

5945-411: Is called a minimal pair for the two alternative phones in question (in this case, [kʰ] and [k] ). The existence of minimal pairs is a common test to decide whether two phones represent different phonemes or are allophones of the same phoneme. To take another example, the minimal pair t ip and d ip illustrates that in English, [t] and [d] belong to separate phonemes, /t/ and /d/ ; since

6090-540: Is considered a separate letter, but accented vowels such as á and é are not. The ll and ch were also formerly considered single letters and sorted separately after l and c , but in 1994, the tenth congress of the Association of Spanish Language Academies changed the collating order so that ll came to be sorted between lk and lm in the dictionary and ch came to be sorted between cg and ci ; those digraphs were still formally designated as letters, but in 2010

6235-500: Is generally predictable) and so it is not phonemic (and therefore not usually indicated in dictionaries). Phonemic tones are found in languages such as Mandarin Chinese in which a given syllable can have five different tonal pronunciations: The tone "phonemes" in such languages are sometimes called tonemes . Languages such as English do not have phonemic tone, but they use intonation for functions such as emphasis and attitude. When

The most universal consonants around the world (that is, the ones appearing in nearly all languages) are the three voiceless stops /p/ , /t/ , /k/ , and the two nasals /m/ , /n/ . However, even these common five are not completely universal. Several languages in the vicinity of the Sahara Desert , including Arabic , lack /p/ . Several languages of North America, such as Mohawk , lack both of

6525-430: Is notoriously a fire in a wooden stove." This approach was opposed to that of Edward Sapir , who gave an important role to native speakers' intuitions about where a particular sound or group of sounds fitted into a pattern. Using English [ŋ] as an example, Sapir argued that, despite the superficial appearance that this sound belongs to a group of three nasal consonant phonemes (/m/, /n/ and /ŋ/), native speakers feel that

6670-408: Is often imperfect, as pronunciations naturally shift in a language over time, rendering previous spelling systems outdated or no longer closely representative of the sounds of the language (see § Correspondence between letters and phonemes below). A phoneme is a sound or a group of different sounds perceived to have the same function by speakers of the language or dialect in question. An example

6815-492: Is possible to discover the phonemes of a language purely by examining the distribution of phonetic segments. Referring to mentalistic definitions of the phoneme, Twaddell (1935) stated "Such a definition is invalid because (1) we have no right to guess about the linguistic workings of an inaccessible 'mind', and (2) we can secure no advantage from such guesses. The linguistic processes of the 'mind' as such are quite simply unobservable; and introspection about linguistic processes

6960-412: Is that the sound spelled with the symbol t is usually articulated with a glottal stop [ʔ] (or a similar glottalized sound) in the word cat , an alveolar flap [ɾ] in dating , an alveolar plosive [t] in stick , and an aspirated alveolar plosive [tʰ] in tie ; however, American speakers perceive or "hear" all of these sounds (usually with no conscious effort) as merely being allophones of

7105-497: Is the English phoneme /k/ , which occurs in words such as c at , k it , s c at , s k it . Although most native speakers do not notice this, in most English dialects, the "c/k" sounds in these words are not identical: in kit [kʰɪt] , the sound is aspirated, but in skill [skɪl] , it is unaspirated. The words, therefore, contain different speech sounds , or phones , transcribed [kʰ] for

7250-584: Is the notation for a sequence of four phonemes, /p/ , /ʊ/ , /ʃ/ , and /t/ , that together constitute the word pushed . Sounds that are perceived as phonemes vary by languages and dialects, so that [ n ] and [ ŋ ] are separate phonemes in English since they distinguish words like sin from sing ( /sɪn/ versus /sɪŋ/ ), yet they comprise a single phoneme in some other languages, such as Spanish, in which [pan] and [paŋ] for instance are merely interpreted by Spanish speakers as regional or dialect-specific ways of pronouncing

7395-423: Is unknown to many Italians because spelling is usually trivial, as Italian spelling is highly phonemic. In standard Spanish, one can tell the pronunciation of a word from its spelling, but not vice versa, as phonemes sometimes can be represented in more than one way, but a given letter is consistently pronounced. French using silent letters , nasal vowels , and elision , may seem to lack much correspondence between

In German, words starting with sch- (which spells the German phoneme / ʃ / ) are inserted between words with initial sca- and sci- (all incidentally loanwords) instead of appearing after the initial sz , as though it were a single letter, which contrasts several languages such as Albanian , in which dh- , ë- , gj- , ll- , rr- , th- , xh-, and zh-, which all represent phonemes and considered separate single letters, would follow

7975-553: The Greek alphabet was the first true alphabet; it was originally derived from the Phoenician alphabet , which was an abjad. Alphabets usually have a standard ordering for their letters. This makes alphabets a useful tool in collation , as words can be listed in a well-defined order—commonly known as alphabetical order . This also means that letters may be used as a method of "numbering" ordered items. Some systems demonstrate acrophony ,

One of the Kru languages , Wobé , has been claimed to have 14, though this is disputed. The most common vowel system consists of the five vowels /i/, /e/, /a/, /o/, /u/ . The most common consonants are /p/, /t/, /k/, /m/, /n/ . Relatively few languages lack any of these consonants, although it does happen: for example, Arabic lacks /p/ , standard Hawaiian lacks /t/ , Mohawk and Tlingit lack /p/ and /m/ , Hupa lacks both /p/ and

The Phoenician system is considered the first true alphabet and is the ultimate ancestor of many modern scripts, including Arabic , Cyrillic , Greek , Hebrew , Latin , and possibly Brahmic . Peter T. Daniels distinguishes true alphabets—which use letters to represent both consonants and vowels—from both abugidas and abjads , which only need letters for consonants. Abjads generally lack vowel indicators altogether, while abugidas represent them with diacritics added to letters. In this narrower sense,

In the narrower sense, some scholars distinguish "true" alphabets from two other types of segmental script, abjads , and abugidas . These three differ in how they treat vowels. Abjads have letters for consonants and leave most vowels unexpressed. Abugidas are also consonant-based but indicate vowels with diacritics ,

But with a few striking exceptions, such as Xavante and Tahitian —which have no dorsal consonants whatsoever—nearly all other languages have at least one velar consonant: most of the few languages that do not have a simple /k/ (that is, a sound that is generally pronounced [k] ) have

Stokoe's terminology and notation system are no longer used by researchers to describe the phonemes of sign languages; William Stokoe 's research, while still considered seminal, has been found not to characterize American Sign Language or other sign languages sufficiently. For instance, non-manual features are not included in Stokoe's classification. More sophisticated models of sign language phonology have since been proposed by Brentari , Sandler , and Van der Kooij.

That is, phonetically they are consonants, but phonemically they behave as vowels. Many Slavic languages allow

The spelling of English does not strictly conform to its phonemes, so that the words knot , nut , and gnat , regardless of spelling, all share the consonant phonemes /n/ and /t/ , differing only by their internal vowel phonemes: /ɒ/ , /ʌ/ , and /æ/ , respectively. Similarly, /pʊʃt/

10295-557: The English names got derived) preserve the qualities of the English vowels before the Great Vowel Shift. By contrast, the names of F, L, M, N, and S ( /ɛf, ɛl, ɛm, ɛn, ɛs/ ) remain the same in both languages because "short" vowels were largely unaffected by the Shift. In Cyrillic, originally, acrophony was present using Slavic words. The first three words going, azŭ, buky, vědě, with the Cyrillic collation order being, А, Б, В. However, this

10440-522: The Great created the Hangul alphabet in 1443 CE. Hangul is a unique alphabet: it is a featural alphabet , where the design of many of the letters comes from a sound's place of articulation, like P looking like the widened mouth and L looking like the tongue pulled in. The creation of Hangul was planned by the government of the day, and it places individual letters in syllable clusters with equal dimensions, in

10585-454: The Latin alphabet. The exception was for decorative use, where the runes remained in use until the 20th century. The Old Hungarian script was the writing system of the Hungarians. It was in use during the entire history of Hungary, albeit not as an official writing system. From the 19th century, it once again became more and more popular. The Glagolitic alphabet was the initial script of

10730-567: The Latin alphabet. Uzbekistan is reforming the alphabet to use diacritics on the letters that are marked by apostrophes and the letters that are digraphs. The standard system of symbols used by linguists to represent sounds in any language, independently of orthography, is called the International Phonetic Alphabet . Zhou, Minglang (2003). Multilingualism in China . doi : 10.1515/9783110924596 . ISBN   978-3-11-017896-8 . Phoneme A phoneme ( / ˈ f oʊ n iː m / )

10875-714: The Northwest Semitic "Abgad" order, is already well established. Although, languages using this alphabet have different conventions for their treatment of modified letters (such as the French é , à , and ô ) and certain combinations of letters ( multigraphs ). In French, these are not considered to be additional letters for collation. However, in Icelandic , the accented letters such as á , í , and ö are considered distinct letters representing different vowel sounds from sounds represented by their unaccented counterparts. In Spanish, ñ

11020-457: The Ugaritic script were the first scripts with a limited number of signs instead of using many different signs for words, in contrast to cuneiform, Egyptian hieroglyphs, and Linear B . The Phoenician script was probably the first phonemic script, and it contained only about two dozen distinct letters, making it a script simple enough for traders to learn. Another advantage of the Phoenician alphabet

11165-597: The alphabet, though some letters and digraphs represent more than one consonant. For example, the sound spelled ⟨th⟩ in "this" is a different consonant from the ⟨th⟩ sound in "thin". (In the IPA, these are [ð] and [θ] , respectively.) The word consonant comes from Latin oblique stem cōnsonant- , from cōnsonāns 'sounding-together', a calque of Greek σύμφωνον sýmphōnon (plural sýmphōna , σύμφωνα ). Dionysius Thrax calls consonants sýmphōna ( σύμφωνα 'sounded with') because in Greek they can only be pronounced with

11310-462: The approach of underspecification would not attempt to assign [ə] to a specific phoneme in some or all of these cases, although it might be assigned to an archiphoneme, written something like //A// , which reflects the two neutralized phonemes in this position, or {a|o} , reflecting its unmerged values. A somewhat different example is found in English, with the three nasal phonemes /m, n, ŋ/ . In word-final position these all contrast, as shown by

11455-477: The appropriate environments) to be realized with the phone [ɾ] (an alveolar flap ). For example, the same flap sound may be heard in the words hi tt ing and bi dd ing , although it is intended to realize the phoneme /t/ in the first word and /d/ in the second. This appears to contradict biuniqueness. For further discussion of such cases, see the next section. Phonemes that are contrastive in certain environments may not be contrastive in all environments. In

11600-436: The aspirated form and [k] for the unaspirated one. These different sounds are nonetheless considered to belong to the same phoneme, because if a speaker used one instead of the other, the meaning of the word would not change: using the aspirated form [kʰ] in skill might sound odd, but the word would still be recognized. By contrast, some other sounds would cause a change in meaning if substituted: for example, substitution of

11745-425: The branch of linguistics known as phonology . The English words cell and set have the exact same sequence of sounds, except for being different in their final consonant sounds: thus, /sɛl/ versus /sɛt/ in the International Phonetic Alphabet (IPA), a writing system that can be used to represent phonemes. Since /l/ and /t/ alone distinguish certain words from others, they are each examples of phonemes of

11890-459: The contrast is lost, since both are reduced to the same sound, usually [ə] (for details, see vowel reduction in Russian ). In order to assign such an instance of [ə] to one of the phonemes /a/ and /o/ , it is necessary to consider morphological factors (such as which of the vowels occurs in other forms of the words, or which inflectional pattern is followed). In some cases even this may not provide an unambiguous answer. A description using

12035-428: The devisers of the alphabet chose not to represent the phonemic effect of vowel length. However, because changes in the spoken language are often not accompanied by changes in the established orthography (as well as other reasons, including dialect differences, the effects of morphophonology on orthography, and the use of foreign spellings for some loanwords ), the correspondence between spelling and pronunciation in

12180-767: The discovery of the Rosetta Stone . There was also cuneiform , primarily used to write several ancient languages, including Sumerian . The last known use of cuneiform was in 75 CE, after which the script fell out of use. In the Middle Bronze Age , an apparently alphabetic system known as the Proto-Sinaitic script appeared in Egyptian turquoise mines in the Sinai Peninsula c.  1840 BCE , apparently left by Canaanite workers. Orly Goldwasser has connected

12325-582: The earlier forms. The script in its classical form was used until the 1st century CE. The Etruscan language itself was not used during the Roman Empire , but the script was used for religious texts. Some adaptations of the Latin alphabet have ligatures , a combination of two letters make one, such as æ in Danish and Icelandic and ⟨ Ȣ ⟩ in Algonquian ; borrowings from other alphabets, such as

12470-402: The entire final -an . While bopomofo is not a mainstream writing system, it is still often used in ways similar to a romanization system, for aiding pronunciation and as an input method for Chinese characters on computers and cellphones. The term "alphabet" is used by linguists and paleographers in both a wide and a narrow sense. In a broader sense, an alphabet is a segmental script at

12615-544: The environments where they do not contrast, the contrast is said to be neutralized . In these positions it may become less clear which phoneme a given phone represents. Absolute neutralization is a phenomenon in which a segment of the underlying representation is not realized in any of its phonetic representations (surface forms). The term was introduced by Paul Kiparsky (1968), and contrasts with contextual neutralization where some phonemes are not contrastive in certain environments. Some phonologists prefer not to specify

12760-477: The first alphabet had developed about that time. The script was based on letter appearances and names, believed to be based on Egyptian hieroglyphs. This script had no characters representing vowels. Originally, it probably was a syllabary—a script where syllables are represented with characters—with symbols that were not needed being removed. The best-attested Bronze Age alphabet is Ugaritic , invented in Ugarit before

12905-434: The following: Some phonotactic restrictions can alternatively be analyzed as cases of neutralization. See Neutralization and archiphonemes below, particularly the example of the occurrence of the three English nasals before stops. Biuniqueness is a requirement of classic structuralist phonemics. It means that a given phone , wherever it occurs, must unambiguously be assigned to one and only one phoneme. In other words,

13050-516: The idea of a cognitive or psycholinguistic function for the phoneme. Later, it was used and redefined in generative linguistics , most famously by Noam Chomsky and Morris Halle , and remains central to many accounts of the development of modern phonology . As a theoretical concept or model, though, it has been supplemented and even replaced by others. Some linguists (such as Roman Jakobson and Morris Halle ) proposed that phonemes may be further decomposable into features , such features being

13195-432: The illiterate turquoise miner graffiti theory to the origin of the alphabet. In 1999, American Egyptologists John and Deborah Darnell discovered an earlier version of this first alphabet at the Wadi el-Hol valley. The script dated to c.  1800 BCE and shows evidence of having been adapted from specific forms of Egyptian hieroglyphs that could be dated to c.  2000 BCE , strongly suggesting that

13340-634: The labials /p/ and /m/ . The Wichita language of Oklahoma and some West African languages, such as Ijo , lack the consonant /n/ on a phonemic level, but do use it phonetically, as an allophone of another consonant (of /l/ in the case of Ijo, and of /ɾ/ in Wichita). A few languages on Bougainville Island and around Puget Sound , such as Makah , lack both of the nasals [m] and [n] altogether, except in special speech registers such as baby-talk. The 'click language' Nǁng lacks /t/ , and colloquial Samoan lacks both alveolars, /t/ and /n/ . Despite

13485-400: The language perceive two sounds as significantly different even if no exact minimal pair exists in the lexicon. It is challenging to find a minimal pair to distinguish English / ʃ / from / ʒ / , yet it seems uncontroversial to claim that the two consonants are distinct phonemes. The two words 'pressure' / ˈ p r ɛ ʃ ər / and 'pleasure' / ˈ p l ɛ ʒ ər / can serve as

13630-449: The letter Y stands for the consonant/semi-vowel /j/ in y oke , the vowel /ɪ/ in m y th , the vowel /i/ in funn y , the diphthong /aɪ/ in sk y , and forms several digraphs for other diphthongs, such as sa y , bo y , ke y . Similarly, R commonly indicates or modifies a vowel in non-rhotic accents . This article is concerned with consonant sounds, however they are written. Consonants and vowels correspond to distinct parts of

13775-447: The letters ⟨d, e, g, l, n, r, t, x, z⟩ respectively, as well as Hungarian and Welsh. Further, German words with an umlaut get collated ignoring the umlaut as—contrary to Turkish , which adopted the graphemes ö and ü , and where a word like tüfek would come after tuz , in the dictionary. An exception is the German telephone directory, where umlauts are sorted like ä = ae since names such as Jäger also appear with

13920-540: The liturgical language Old Church Slavonic and became, together with the Greek uncial script, the basis of the Cyrillic script . Cyrillic is one of the most widely used modern alphabetic scripts and is notable for its use in Slavic languages and also for other languages within the former Soviet Union . Cyrillic alphabets include Serbian , Macedonian , Bulgarian , Russian , Belarusian , and Ukrainian . The Glagolitic alphabet

14065-532: The mapping between phones and phonemes is required to be many-to-one rather than many-to-many . The notion of biuniqueness was controversial among some pre- generative linguists and was prominently challenged by Morris Halle and Noam Chomsky in the late 1950s and early 1960s. An example of the problems arising from the biuniqueness requirement is provided by the phenomenon of flapping in North American English . This may cause either /t/ or /d/ (in

14210-406: The meaning of a word. In those languages, therefore, the two sounds represent different phonemes. For example, in Icelandic , [kʰ] is the first sound of kátur , meaning "cheerful", but [k] is the first sound of gátur , meaning "riddles". Icelandic, therefore, has two separate phonemes /kʰ/ and /k/ . A pair of words like kátur and gátur (above) that differ only in one phone

14355-489: The minimal triplet sum /sʌm/ , sun /sʌn/ , sung /sʌŋ/ . However, before a stop such as /p, t, k/ (provided there is no morpheme boundary between them), only one of the nasals is possible in any given position: /m/ before /p/ , /n/ before /t/ or /d/ , and /ŋ/ before /k/ , as in limp, lint, link ( /lɪmp/ , /lɪnt/ , /lɪŋk/ ). The nasals are therefore not contrastive in these environments, and according to some theorists this makes it inappropriate to assign

14500-535: The most common vowel is not marked in Indic abugidas. In Zhuyin , not only is one of the tones unmarked; but there is a diacritic to indicate a lack of tone, like the virama of Indic. Alphabets often come to be associated with a standard ordering of their letters; this is for collation —namely, for listing words and other items in alphabetical order . The ordering of the Latin alphabet ( A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ), which derives from

14645-479: The most common, and a liquid consonant or two, with /l/ the most common. The approximant /w/ is also widespread, and virtually all languages have one or more nasals , though a very few, such as the Central dialect of Rotokas , lack even these. This last language has the smallest number of consonants in the world, with just six. In rhotic American English, the consonants spoken most frequently are /n, ɹ, t/ . ( /ɹ/

14790-415: The nasal phones heard here to any one of the phonemes (even though, in this case, the phonetic evidence is unambiguous). Instead they may analyze these phonemes as belonging to a single archiphoneme, written something like //N// , and state the underlying representations of limp, lint, link to be //lɪNp//, //lɪNt//, //lɪNk// . This latter type of analysis is often associated with Nikolai Trubetzkoy of

14935-650: The nucleus of a syllable. This may be the case for words such as church in rhotic dialects of English, although phoneticians differ in whether they consider this to be a syllabic consonant, /ˈtʃɹ̩tʃ/ , or a rhotic vowel, /ˈtʃɝtʃ/ : Some distinguish an approximant /ɹ/ that corresponds to a vowel /ɝ/ , for rural as /ˈɹɝl/ or [ˈɹʷɝːl̩] ; others see these as a single phoneme, /ˈɹɹ̩l/ . Other languages use fricative and often trilled segments as syllabic nuclei, as in Czech and several languages in Democratic Republic of

15080-636: The number of identifiably different sounds. Different languages vary considerably in the number of phonemes they have in their systems (although apparent variation may sometimes result from the different approaches taken by the linguists doing the analysis). The total phonemic inventory in languages varies from as few as 9–11 in Pirahã and 11 in Rotokas to as many as 141 in ǃXũ . The number of phonemically distinct vowels can be as low as two, as in Ubykh and Arrernte . At

15225-556: The other extreme, the Bantu language Ngwe has 14 vowel qualities, 12 of which may occur long or short, making 26 oral vowels, plus six nasalized vowels, long and short, making a total of 38 vowels; while !Xóõ achieves 31 pure vowels, not counting its additional variation by vowel length, by varying the phonation . As regards consonant phonemes, Puinave and the Papuan language Tauade each have just seven, and Rotokas has only six. !Xóõ , on

15370-461: The other hand, has somewhere around 77, and Ubykh 81. The English language uses a rather large set of 13 to 21 vowel phonemes, including diphthongs, although its 22 to 26 consonants are close to average. Across all languages, the average number of consonant phonemes per language is about 22, while the average number of vowel phonemes is about 8. Some languages, such as French , have no phonemic tone or stress , while Cantonese and several of

15515-501: The other, HMĦLQ, was used in southern Arabia and is preserved today in Geʻez . Both orders have therefore been stable for at least 3000 years. Runic used an unrelated Futhark sequence, which got simplified later on. Arabic usually uses its sequence, although Arabic retains the traditional abjadi order , which is used for numbers. The Brahmic family of alphabets used in India uses

15660-449: The phoneme /ʃ/ ). Also a single letter may represent two phonemes, as in English ⟨x⟩ representing /gz/ or /ks/ . There may also exist spelling/pronunciation rules (such as those for the pronunciation of ⟨c⟩ in Italian ) that further complicate the correspondence of letters to phonemes, although they need not affect the ability to predict the pronunciation from

15805-785: The phoneme, linguists have proposed other sorts of underlying objects, giving them names with the suffix -eme , such as morpheme and grapheme . These are sometimes called emic units . The latter term was first used by Kenneth Pike , who also generalized the concepts of emic and etic description (from phonemic and phonetic respectively) to applications outside linguistics. Languages do not generally allow words or syllables to be built of any arbitrary sequences of phonemes. There are phonotactic restrictions on which sequences of phonemes are possible and in which environments certain phonemes can occur. Phonemes that are significantly limited by such restrictions may be called restricted phonemes . In English, examples of such restrictions include

15950-418: The position expressed by Kenneth Pike : "There is only one accurate phonemic analysis for a given set of data", while others believed that different analyses, equally valid, could be made for the same data. Yuen Ren Chao (1934), in his article "The non-uniqueness of phonemic solutions of phonetic systems" stated "given the sounds of a language, there are usually more than one possible way of reducing them to

16095-402: The problem of dialects by associating the alphabet with the national standard. Some national languages like Finnish , Armenian , Turkish , Russian, Serbo-Croatian ( Serbian , Croatian , and Bosnian ), and Bulgarian have a very regular spelling system with nearly one-to-one correspondence between letters and phonemes. Similarly, the Italian verb corresponding to 'spell (out),' compitare ,

16240-430: The right in a cell are voiced , to the left are voiceless . Shaded areas denote articulations judged impossible. Legend: unrounded  •  rounded Alphabet An alphabet is a standard set of letters written to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in

16385-425: The same period there was disagreement about the correct basis for a phonemic analysis. The structuralist position was that the analysis should be made purely on the basis of the sound elements and their distribution, with no reference to extraneous factors such as grammar, morphology or the intuitions of the native speaker; this position is strongly associated with Leonard Bloomfield . Zellig Harris claimed that it

16530-501: The same phoneme. However, they are so dissimilar phonetically that they are considered separate phonemes. A case like this shows that sometimes it is the systemic distinctions and not the lexical context which are decisive in establishing phonemes. This implies that the phoneme should be defined as the smallest phonological unit which is contrastive at a lexical level or distinctive at a systemic level. Phonologists have sometimes had recourse to "near minimal pairs" to show that speakers of

16675-560: The same way as Chinese characters . This change allows for mixed-script writing, where one syllable always takes up one type space no matter how many letters get stacked into building that one sound-block. Bopomofo , also referred to as zhuyin , is a semi-syllabary used primarily in Taiwan to transcribe the sounds of Standard Chinese . Following the proclamation of the People's Republic of China in 1949 and its adoption of Hanyu Pinyin in 1956,

16820-613: The same word ( pan : the Spanish word for "bread"). Such spoken variations of a single phoneme are known by linguists as allophones . Linguists use slashes in the IPA to transcribe phonemes but square brackets to transcribe more precise pronunciation details, including allophones; they describe this basic distinction as phonemic versus phonetic . Thus, the pronunciation patterns of tap versus tab , or pat versus bat , can be represented phonemically and are written between slashes (including /p/ , /b/ , etc.), while nuances of exactly how

16965-513: The same, but one of the parameters changes. However, the absence of minimal pairs for a given pair of phones does not always mean that they belong to the same phoneme: they may be so dissimilar phonetically that it is unlikely for speakers to perceive them as the same sound. For example, English has no minimal pair for the sounds [h] (as in h at ) and [ŋ] (as in ba ng ), and the fact that they can be shown to be in complementary distribution could be used to argue for their being allophones of

17110-412: The sound [t] would produce the different word s t ill , and that sound must therefore be considered to represent a different phoneme (the phoneme /t/ ). The above shows that in English, [k] and [kʰ] are allophones of a single phoneme /k/ . In some languages, however, [kʰ] and [k] are perceived by native speakers as significantly different sounds, and substituting one for the other can change

17255-495: The spelling Jaeger and are not distinguished in the spoken language. The Danish and Norwegian alphabets end with ⟨æ, ø, å⟩ , whereas the Swedish conventionally put ⟨å, ä, ö⟩ at the end. However, æ phonetically corresponds with ⟨ä⟩ , as does ⟨ø⟩ and ⟨ö⟩ . It is unknown whether the earliest alphabets had a defined sequence. Some alphabets today, such as

17400-499: The spelling and pronunciation. However, its rules on pronunciation, though complex, are consistent and predictable with a fair degree of accuracy. At the other extreme are languages such as English, where pronunciations mostly have to be memorized as they do not correspond to the spelling consistently. For English, this is because the Great Vowel Shift occurred after the orthography got established and because English has acquired

17545-641: The spelling and vice versa, provided the rules are consistent. Sign language phonemes are bundles of articulation features. Stokoe was the first scholar to describe the phonemic system of ASL . He identified the bundles tab (elements of location, from Latin tabula ), dez (the handshape, from designator ), and sig (the motion, from signation ). Some researchers also discern ori (orientation), facial expression or mouthing . Just as with spoken languages, when features are combined, they create phonemes. As in spoken languages, sign languages have minimal pairs which differ in only one phoneme. For instance,

17690-442: The study of sign languages . A chereme , as the basic unit of signed communication, is functionally and psychologically equivalent to the phonemes of oral languages, and has been replaced by that term in the academic literature. Cherology , as the study of cheremes in language, is thus equivalent to phonology. The terms are not in use anymore. Instead, the terms phonology and phoneme (or distinctive feature ) are used to stress

17835-499: The surface form that is actually uttered and heard. Allophones each have technically different articulations inside particular words or particular environments within words , yet these differences do not create any meaningful distinctions. Alternatively, at least one of those articulations could be feasibly used in all such words with these words still being recognized as such by users of the language. An example in American English

17980-575: The syllable nucleus, as the i in English boil [ˈbɔɪ̯l] . On the other, there are approximants that behave like consonants in forming onsets, but are articulated very much like vowels, as the y in English yes [ˈjɛs] . Some phonologists model these as both being the underlying vowel /i/ , so that the English word bit would phonemically be /bit/ , beet would be /bii̯t/ , and yield would be phonemically /i̯ii̯ld/ . Likewise, foot would be /fut/ , food would be /fuu̯d/ , wood would be /u̯ud/ , and wooed would be /u̯uu̯d/ . However, there

18125-527: The term zed for Z in all forms of English, other than American English. Over time names sometimes shifted or were added, as in double U for W , or "double V" in French, the English name for Y, and the American zee for Z. Comparing them in English and French gives a clear reflection of the Great Vowel Shift : A, B, C, and D are pronounced /eɪ, biː, siː, diː/ in today's English, but in contemporary French they are /a, be, se, de/ . The French names (from which

18270-643: The trill [r̩] and the lateral [l̩] as syllabic nuclei (see Words without vowels ). In languages like Nuxalk , it is difficult to know what the nucleus of a syllable is, or if all syllables even have nuclei. If the concept of 'syllable' applies in Nuxalk, there are syllabic consonants in words like /sx̩s/ ( /s̩xs̩/ ?) 'seal fat'. Miyako in Japan is similar, with /f̩ks̩/ 'to build' and /ps̩ks̩/ 'to pull'. Each spoken consonant can be distinguished by several phonetic features : All English consonants can be classified by

18415-405: The true minimal constituents of language. Features overlap each other in time, as do suprasegmental phonemes in oral language and many phonemes in sign languages. Features could be characterized in different ways: Jakobson and colleagues defined them in acoustic terms, Chomsky and Halle used a predominantly articulatory basis, though retaining some acoustic features, while Ladefoged 's system

18560-520: The use of bopomofo on the mainland is limited. Bopomofo developed from a form of Chinese shorthand based on Chinese characters in the early 1900s and has elements of both an alphabet and a syllabary. Like an alphabet, the phonemes of syllable initials are represented by individual symbols, but like a syllabary, the phonemes of the syllable finals are not; each possible final (excluding the medial glide ) has its own character, an example being luan written as ㄌㄨㄢ ( l-u-an ). The last symbol ㄢ takes place as

18705-504: The various types. Some alphabets disregard tone entirely, especially when it does not carry a heavy functional load, as in Somali and many other languages of Africa and the Americas. Most commonly, tones are indicated by diacritics, which is how vowels are treated in abugidas, which is the case for Vietnamese (a true alphabet) and Thai (an abugida). In Thai, the tone is determined primarily by

18850-403: The velar nasal is really the sequence [ŋɡ]/. The theory of generative phonology which emerged in the 1960s explicitly rejected the structuralist approach to phonology and favoured the mentalistic or cognitive view of Sapir. These topics are discussed further in English phonology#Controversial issues . Phonemes are considered to be the basis for alphabetic writing systems. In such systems

18995-554: The vowel normally transcribed /aɪ/ would instead be /aj/ , /aʊ/ would be /aw/ and /ɑː/ would be /ah/ , or /ar/ in a rhotic accent if there is an ⟨r⟩ in the spelling. It is also possible to treat English long vowels and diphthongs as combinations of two vowel phonemes, with long vowels treated as a sequence of two short vowels, so that 'palm' would be represented as /paam/. English can thus be said to have around seven vowel phonemes, or even six if schwa were treated as an allophone of /ʌ/ or of other short vowels. In

19140-508: The vowels is mandatory, and whole letters are used, so the script is a true alphabet. Other languages may use a Semitic abjad with forced vowel diacritics, effectively making them abugidas. On the other hand, the ʼPhags-pa script of the Mongol Empire was based closely on the Tibetan abugida , but vowel marks are written after the preceding consonant rather than as diacritic marks. Although short

19285-417: The words betting and bedding might both be pronounced [ˈbɛɾɪŋ] . Under the generative grammar theory of linguistics, if a speaker applies such flapping consistently, morphological evidence (the pronunciation of the related forms bet and bed , for example) would reveal which phoneme the flap represents, once it is known which morpheme is being used. However, other theorists would prefer not to make such

19430-410: The words have different meanings, English-speakers must be conscious of the distinction between the two sounds. Signed languages, such as American Sign Language (ASL), also have minimal pairs, differing only in (exactly) one of the signs' parameters: handshape, movement, location, palm orientation, and nonmanual signal or marker. A minimal pair may exist in the signed language if the basic sign stays

19575-446: The world's languages, and perhaps the primary pattern in all of them. However, the distinction between consonant and vowel is not always clear cut: there are syllabic consonants and non-syllabic vowels in many of the world's languages. One blurry area is in segments variously called semivowels , semiconsonants , or glides . On one side, there are vowel-like segments that are not in themselves syllabic, but form diphthongs as part of

19720-411: The world. The Etruscan alphabet remained nearly unchanged for several hundred years. Only evolving once the Etruscan language changed itself. The letters used for non-existent phonemes were dropped. Afterwards, however, the alphabet went through many different changes. The final classical form of Etruscan contained 20 letters. Four of them are vowels— ⟨a, e, i, u⟩ —six fewer letters than

19865-486: The world. The discovery suggests that the alphabet emerged 500 years earlier than previously thought, and undermines leading ideas about how it was invented. According to Christopher Rollston , a scholar of the ancient Near East, the morphology of the letters on the cylinder seals parallels quite nicely that of the existing corpus of early alphabetic writing. This theory however has yet to be universally accepted. The English word alphabet came into Middle English from

20010-670: The writing with the contemporary spoken language. These can range from simple spelling changes and word forms to switching the entire writing system. For example, Turkey switched from the Arabic alphabet to a Latin-based Turkish alphabet , and Kazakh changed from an Arabic script to a Cyrillic script due to the Soviet Union's influence. In 2021, it made a transition to the Latin alphabet, similar to Turkish. The Cyrillic script used to be official in Uzbekistan and Turkmenistan before they switched to

20155-399: The written symbols ( graphemes ) represent, in principle, the phonemes of the language being written. This is most obviously the case when the alphabet was invented with a particular language in mind; for example, the Latin alphabet was devised for Classical Latin, and therefore the Latin of that period enjoyed a near one-to-one correspondence between phonemes and graphemes in most cases, though

20300-679: Was fonema , the basic unit of what they called psychophonetics . Daniel Jones became the first linguist in the western world to use the term phoneme in its current sense, employing the word in his article "The phonetic structure of the Sechuana Language". The concept of the phoneme was then elaborated in the works of Nikolai Trubetzkoy and others of the Prague School (during the years 1926–1935), and in those of structuralists like Ferdinand de Saussure , Edward Sapir , and Leonard Bloomfield . Some structuralists (though not Sapir) rejected

20445-411: Was abandoned in Latin . It referred to the letters by adding a vowel—usually ⟨e⟩ , sometimes ⟨a⟩ or ⟨u⟩ —before or after the consonant. Two exceptions were Y and Z , which were borrowed from the Greek alphabet rather than Etruscan. They were known as Y Graeca "Greek Y" and zeta (from Greek)—this discrepancy was inherited by many European languages, as in

20590-476: Was descended. Abugidas are writing systems with characters comprising consonant–vowel sequences. Alphabets without obligatory vowels are called abjads , with examples being Arabic, Hebrew, and Syriac . The omission of vowels was not always a satisfactory solution due to the need of preserving sacred texts. "Weak" consonants are used to indicate vowels. These letters have a dual function since they can also be used as pure consonants. The Proto-Sinaitic script and

20735-412: Was later abandoned in favor of a system similar to Latin. When an alphabet is adopted or developed to represent a given language, an orthography generally comes into being, providing rules for spelling words, following the principle on which alphabets get based. These rules will map letters of the alphabet to the phonemes of the spoken language. In a perfectly phonemic orthography , there would be

20880-542: Was that it could write different languages since it recorded words phonemically. The Phoenician script was spread across the Mediterranean by the Phoenicians. The Greek alphabet was the first in which vowels had independent letterforms separate from those of consonants. The Greeks chose letters representing sounds that did not exist in Phoenician to represent vowels. The Linear B syllabary, used by Mycenaean Greeks from

21025-404: Was used until the 5th century CE, and fundamentally differed by adding pronunciation hints to existing hieroglyphs that had previously carried no pronunciation information. Later on, these phonemic symbols also became used to transcribe foreign words. The first fully phonemic script was the Proto-Sinaitic script , also descending from Egyptian hieroglyphs, which was later modified to create
