121-846: Writing systems are generally classified according to how its symbols, called graphemes , generally relate to units of language. Phonetic writing systems, which include alphabets and syllabaries , use graphemes that correspond to sounds in the corresponding spoken language . Alphabets use graphemes called letters that generally correspond to spoken phonemes , and are typically classified into three categories. In general, pure alphabets use letters to represent both consonant and vowel sounds, while abjads only have letters representing consonants, and abugidas use characters corresponding to consonant–vowel pairs. Syllabaries use graphemes called syllabograms that represent entire syllables or moras . By contrast, logographic (alternatively morphographic ) writing systems use graphemes that represent

242-465: A featural system uses symbols representing sub-phonetic elements—e.g. those traits that can be used to distinguish between and analyse a language's phonemes, such as their voicing or place of articulation . The only prominent example of a featural system is the hangul script used to write Korean, where featural symbols are combined into letters, which are in turn joined into syllabic blocks. Many scholars, including John DeFrancis (1911–2009), reject

363-556: A certain amount of deviation from the ideal of exact grapheme–phoneme correspondence. A phoneme may be represented by a multigraph (sequence of more than one grapheme), as the digraph sh represents a single sound in English (and sometimes a single grapheme may represent more than one phoneme, as with the Russian letter я or the Spanish c). Some graphemes may not represent any sound at all (like

484-574: A characterization of hangul as a featural system—with arguments including that Korean writers do not themselves think in these terms when writing—or question the viability of Sampson's category altogether. As hangul was consciously created by literate experts, Daniels characterizes it as a "sophisticated grammatogeny "—a writing system intentionally designed for a specific purpose, as opposed to having evolved gradually over time. Other grammatogenies include shorthands developed by professionals and constructed scripts created by hobbyists and creatives, like

605-415: A component related to the character's meaning, and a component that gives a hint for its pronunciation. A syllabary is a set of written symbols that represent either syllables or moras —a unit of prosody that is often but not always a syllable in length. The graphemes used in syllabaries are called syllabograms . Syllabaries are best suited to languages with relatively simple syllable structure, since

726-499: 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

847-477: A different symbol is needed for every syllable. Japanese, for example, contains about 100 moras, which are represented by moraic hiragana . By contrast, English features complex syllable structures with a relatively large inventory of vowels and complex consonant clusters —making for a total of 15–16,000 distinct syllables. Some syllabaries have larger inventories: the Yi script contains 756 different symbols. An alphabet

968-417: A five-fold classification of writing systems, comprising pictographic scripts, ideographic scripts, analytic transitional scripts, phonetic scripts, and alphabetic scripts. In practice, writing systems are classified according to the primary type of symbols used, and typically include exceptional cases where symbols function differently. For example, logographs found within phonetic systems like English include

1089-462: 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

1210-406: 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

1331-483: 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

1452-401: 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

1573-407: A set of defined graphemes, collectively called a script . The concept of the grapheme is similar to that of the phoneme used in the study of spoken languages. Likewise, as many sonically distinct phones may function as the same phoneme depending on speaker, dialect, and context, many visually distinct glyphs (or graphs ) may be identified as the same grapheme. These variant glyphs are known as

1694-417: 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

1815-456: 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

1936-435: 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

2057-503: A single phoneme are normally treated as combinations of separate letters, not as graphemes in their own right. However, in some languages a multigraph may be treated as a single unit for the purposes of collation ; for example, in a Czech dictionary, the section for words that start with ⟨ch⟩ comes after that for ⟨h⟩ . For more examples, see Alphabetical order § Language-specific conventions . Phoneme A phoneme ( / ˈ f oʊ n iː m / )

2178-512: 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

2299-411: 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

2420-542: 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

2541-528: A spoken language, this functions as literacy in a second, acquired language. A single language (e.g. Hindustani ) can be written using multiple writing systems, and a writing system can also represent multiple languages. For example, Chinese characters have been used to write multiple languages throughout the Sinosphere —including the Vietnamese language from at least the 13th century, until their replacement with

2662-417: 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

2783-452: 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

2904-418: 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

3025-488: Is a set of letters , each of which generally represent one of the segmental phonemes in a spoken language. However, these correspondences are rarely uncomplicated, and spelling is often mediated by other factors than just which sounds are used by a speaker. The word alphabet is derived from alpha and beta , the names for the first two letters in the Greek alphabet . An abjad is an alphabet whose letters only represent

3146-414: 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

3267-439: 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

3388-434: Is a visual and tactile notation representing language . The symbols used in writing correspond systematically to functional units of either a spoken or signed language . This definition excludes a broader class of symbolic markings, such as drawings and maps. A text is any instance of written material, including transcriptions of spoken material. The act of composing and recording a text may be referred to as writing , and

3509-414: Is abstract and similar to the notion in computing of a character . By comparison, a specific shape that represents any particular grapheme in a given typeface is called a glyph . There are two main opposing grapheme concepts. In the so-called referential conception , graphemes are interpreted as the smallest units of writing that correspond with sounds (more accurately phonemes ). In this concept,

3630-467: Is an alphabetic writing system whose basic signs denote consonants with an inherent vowel and where consistent modifications of the basic sign indicate other following vowels than the inherent one. In an abugida, there may be a sign for k with no vowel, but also one for ka (if a is the inherent vowel), and ke is written by modifying the ka sign in a consistent way with how la would be modified to get le . In many abugidas, modification consists of

3751-523: Is analogous to the slash notation /a/ used for phonemes . Analogous to the square bracket notation [a] used for phones , glyphs are sometimes denoted with vertical lines, e.g. | ɑ | . In the same way that the surface forms of phonemes are speech sounds or phones (and different phones representing the same phoneme are called allophones ), the surface forms of graphemes are glyphs (sometimes graphs ), namely concrete written representations of symbols (and different glyphs representing

3872-417: 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

3993-641: 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

4114-427: Is associated with the autonomy hypothesis which holds that writing is a system in its own right and should be studied independently from speech. Both concepts have weaknesses. Some models adhere to both concepts simultaneously by including two individual units, which are given names such as graphemic grapheme for the grapheme according to the analogical conception ( h in shake ), and phonological-fit grapheme for

4235-411: 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

4356-450: Is defined as a potentially permanent means of recording information, then these systems do not qualify as writing at all, since the symbols disappear as soon as they are used. Instead, these transient systems serve as signals . Writing systems may be characterized by how text is graphically divided into lines, which are to be read in sequence: For example, English and many other Western languages are written in horizontal rows that begin at

4477-500: 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 Mesoamerican writing systems , including Olmec and the Maya script , were also invented independently. The first known alphabetic writing appeared before 2000 BC, and was used to write a Semitic language spoken in

4719-430: 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

4840-408: 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

4961-492: 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

5082-406: Is some disagreement as to whether capital and lower case letters are allographs or distinct graphemes. Capitals are generally found in certain triggering contexts that do not change the meaning of a word: a proper name, for example, or at the beginning of a sentence, or all caps in a newspaper headline. In other contexts, capitalization can determine meaning: compare, for example Polish and polish :

The name abugida is derived from the first four characters of an order of the Geʽez script used in some contexts. It was coined as a linguistic term by Peter T.

5445-497: 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

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

5687-994: Is used in various models either as a synonym for "morphographic", or as a specific subtype where the basic unit of meaning written is the word . Even with morphographic writing, there remains a correspondence between graphemes and the sounds of speech, but the pronunciation values of the units of meaning is not what is being encoded firstly by the writing system. Many classifications define three primary categories, where phonographic systems are subdivided into syllabic and alphabetic (or segmental ) systems. Syllabaries use symbols called syllabograms to represent syllables or moras . Alphabets use symbols called letters that correspond to spoken phonemes—or more technically to diaphonemes . Alphabets are generally classified into three subtypes, with abjads having letters for consonants , pure alphabets having letters for both consonants and vowels , and abugidas having characters that correspond to consonant–vowel pairs. David Diringer proposed

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

Other ways the second of these has been notated include |m-n-ŋ| , {m, n, ŋ} and //n*// . Another example from English, but this time involving complete phonetic convergence as in the Russian example, is the flapping of /t/ and /d/ in some American English (described above under Biuniqueness ).

Descendants include the Phoenician alphabet ( c.  1050 BC ), and its child in the Greek alphabet ( c.  800 BC ). The Latin alphabet , which descended from the Greek alphabet, is by far the most common script used by writing systems. Several approaches have been taken to classify writing systems, with

Multigraphs representing

This referential concept is linked to the dependency hypothesis that claims that writing merely depicts speech. By contrast, the analogical concept defines graphemes analogously to phonemes, i.e. via written minimal pairs such as shake vs. snake . In this example, h and n are graphemes because they distinguish two words. This analogical concept

As each character represents a single unit of meaning, many different logograms are required to write all the words of a language.

The relationship between writing and language more broadly has been the subject of philosophical analysis as early as Aristotle (384–322 BC). While the use of language is universal across human societies, writing is not—having first emerged much more recently, and only having been independently invented in a handful of locations throughout history. While most spoken languages have not been written, all written languages have been predicated on an existing spoken language.

The morphology of Semitic languages is particularly suited to this approach, as the denotation of vowels is generally redundant. Optional markings for vowels may be used for some abjads, but are generally limited to applications like education. Many pure alphabets were derived from abjads through

8954-459: 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

9075-430: The corner of a stone. The ancient Libyco-Berber alphabet was also written from bottom to top. Grapheme In linguistics , a grapheme is the smallest functional unit of a writing system . The word grapheme is derived from Ancient Greek gráphō ('write'), and the suffix -eme by analogy with phoneme and other emic units . The study of graphemes is called graphemics . The concept of graphemes

9196-428: 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

9317-512: The earliest true writing, closely followed by the Egyptian hieroglyphs . It is generally agreed that the two systems were invented independently from one another; both evolved from proto-writing systems between 3400 and 3200 BC, with the earliest coherent texts dated c.  2600 BC . Chinese characters emerged independently in the Yellow River valley c.  1200 BC . There

9438-544: 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

9559-434: 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,

9680-437: The former is a language, the latter is for shining shoes. Some linguists consider digraphs like the ⟨sh⟩ in ship to be distinct graphemes, but these are generally analyzed as sequences of graphemes. Non-stylistic ligatures , however, such as ⟨æ⟩ , are distinct graphemes, as are various letters with distinctive diacritics , such as ⟨ç⟩ . Identical glyphs may not always represent

9801-419: The grapheme according to the referential concept ( sh in shake ). In newer concepts, in which the grapheme is interpreted semiotically as a dyadic linguistic sign , it is defined as a minimal unit of writing that is both lexically distinctive and corresponds with a linguistic unit ( phoneme , syllable , or morpheme ). Graphemes are often notated within angle brackets : e.g. ⟨a⟩ . This

9922-473: The hand is to the right side of the pen. The Greek alphabet and its successors settled on a left-to-right pattern, from the top to the bottom of the page. Other scripts, such as Arabic and Hebrew , came to be written right-to-left . Scripts that historically incorporate Chinese characters have traditionally been written vertically in columns arranged from right to left, while a horizontal writing direction in rows from left to right became widely adopted only in

10043-516: 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

10164-400: 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

10285-532: 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

10406-457: 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

10527-489: 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

10648-441: The most common based on what unit of language is represented by each unit of writing. At the highest level, writing systems are either phonographic ( lit.   ' sound writing ' ) when graphemes represent units of sound in a language, or morphographic ( lit.   ' form writing ' ) when graphemes represent units of meaning, such as words or morphemes . The term logographic ( lit.   ' word writing ' )

10769-415: 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

10890-636: 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

11011-598: The other cannot change the meaning of a word, they are considered to be allographs of the same grapheme, which can be written ⟨a⟩ . Similarly, the grapheme corresponding to "Arabic numeral zero" has a unique semantic identity and Unicode value U+0030 but exhibits variation in the form of slashed zero . Italic and bold face forms are also allographic, as is the variation seen in serif (as in Times New Roman ) versus sans-serif (as in Helvetica ) forms. There

11132-556: 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

11253-461: 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

11374-449: 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

11495-785: 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

11616-418: 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

11737-407: The same grapheme are called allographs ). Thus, a grapheme can be regarded as an abstraction of a collection of glyphs that are all functionally equivalent. For example, in written English (or other languages using the Latin alphabet ), there are two different physical representations of the lowercase Latin letter "a": " a " and " ɑ ". Since, however, the substitution of either of them for

11858-745: The same grapheme. For example, the three letters ⟨A⟩ , ⟨А⟩ and ⟨Α⟩ appear identical but each has a different meaning: in order, they are the Latin letter A , the Cyrillic letter Azǔ/Азъ and the Greek letter Alpha . Each has its own code point in Unicode: U+0041 A LATIN CAPITAL LETTER A , U+0410 А CYRILLIC CAPITAL LETTER A and U+0391 Α GREEK CAPITAL LETTER ALPHA . The principal types of graphemes are logograms (more accurately termed morphograms ), which represent words or morphemes (for example Chinese characters ,

11979-425: 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

12100-501: 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

12221-563: 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

12342-513: 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

12463-483: The script. Braille is a non-linear adaptation of the Latin alphabet that completely abandoned the Latin forms. The letters are composed of raised bumps on the writing substrate , which can be leather, stiff paper, plastic or metal. There are also transient non-linear adaptations of the Latin alphabet, including Morse code , the manual alphabets of various sign languages , and semaphore, in which flags or bars are positioned at prescribed angles. However, if "writing"

12584-412: 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

12705-438: The space, and other typographic symbols . Ancient logographic scripts often used silent determinatives to disambiguate the meaning of a neighboring (non-silent) word. As mentioned in the previous section, in languages that use alphabetic writing systems, many of the graphemes stand in principle for the phonemes (significant sounds) of the language. In practice, however, the orthographies of such languages entail at least

12826-641: 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,

12947-468: The spoken language in its entirety. Writing systems were preceded by proto-writing systems consisting of ideograms and early mnemonic symbols. The best-known examples include: Writing has been invented independently multiple times in human history. The first writing systems emerged during the Early Bronze Age , with the cuneiform writing system used to write Sumerian generally considered to be

13068-442: 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

13189-499: 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

13310-451: The text, the time available for writing, the intended audience, and the largely unconscious features of an individual's handwriting. Orthography ( lit.   ' correct writing ' ) refers to the rules and conventions for writing shared by a community, including the ordering of and relationship between graphemes. Particularly for alphabets , orthography includes the concept of spelling . For example, English orthography includes

13431-443: The top of a page and end at the bottom, with each row read from left to right. Egyptian hieroglyphs were written either left to right or right to left, with the animal and human glyphs turned to face the beginning of the line. The early alphabet could be written in multiple directions: horizontally from side to side, or vertically. Prior to standardization, alphabetic writing could be either left-to-right (LTR) and right-to-left (RTL). It

13552-405: 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

13673-501: The units of meaning in a language, such as its words or morphemes . Alphabets typically use fewer than 100 distinct symbols, while syllabaries and logographies may use hundreds or thousands respectively. A writing system also includes any punctuation used to aid readers and encode additional meaning, including that which would be communicated in speech via qualities of rhythm , tone , pitch , accent , inflection , or intonation . According to most contemporary definitions, writing

13794-403: 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

13915-554: 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

14036-417: 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

14157-410: 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

14278-399: 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

14399-679: 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

14520-433: Was most commonly written boustrophedonically : starting in one (horizontal) direction, then turning at the end of the line and reversing direction. The right-to-left direction of the Phoenician alphabet initially stabilized after c.  800 BC . Left-to-right writing has an advantage that, since most people are right-handed , the hand does not interfere with text being written—which might not yet have dried—since

14641-409: Was not linear, its Sumerian ancestors were. Non-linear systems are not composed of lines, no matter what instrument is used to write them. Cuneiform was likely the earliest non-linear writing. Its glyphs were formed by pressing the end of a reed stylus into moist clay, not by tracing lines in the clay with the stylus as had been done previously. The result was a radical transformation of the appearance of
