48-455: Gamma Doradus , Latinized from γ Doradus , is the third-brightest star in the southern constellation of Dorado . It is faintly visible to the naked eye with an apparent visual magnitude of approximately 4.25, and is a variable star , the prototype of the class of Gamma Doradus variables . The star is located at a distance of 67  light years from the Sun based on parallax , and

96-513: A stressed syllable . Pronouncing them as unaspirated in these positions, as is done by many Indian English speakers, may make them get confused with the corresponding voiced stop by other English-speakers. Conversely, this confusion does not happen with the native speakers of languages which have aspirated and unaspirated but not voiced stops, such as Mandarin Chinese . S+consonant clusters may vary between aspirated and nonaspirated depending upon if

144-555: A few Tibeto-Burman languages , some Oto-Manguean languages , the Hmongic language Hmu , the Siouan language Ofo , and the Chumashan languages Barbareño and Ventureño . Some languages, such as Choni Tibetan , have as many as four contrastive aspirated fricatives [sʰ] [ɕʰ] , [ʂʰ] and [xʰ] . True aspirated voiced consonants, as opposed to murmured (breathy-voice) consonants such as

192-546: A four-way distinction in stops: voiceless, aspirated, voiced, and voiced aspirated, such as /p pʰ b bʱ/ . Punjabi has lost voiced aspirated consonants, which resulted in a tone system , and therefore has a distinction between voiceless, aspirated, and voiced: /p pʰ b/ . Other languages such as Telugu , Malayalam , and Kannada , have a distinction between voiced and voiceless, aspirated and unaspirated. Most dialects of Armenian have aspirated stops, and some have breathy-voiced stops. Classical and Eastern Armenian have

240-1081: A stressed syllable. In many languages, such as Hindi , tenuis and aspirated consonants are phonemic . Unaspirated consonants like [p˭ s˭] and aspirated consonants like [pʰ ʰp sʰ] are separate phonemes, and words are distinguished by whether they have one or the other. Alemannic German dialects have unaspirated [p˭ t˭ k˭] as well as aspirated [pʰ tʰ kʰ] ; the latter series are usually viewed as consonant clusters . French , Standard Dutch , Afrikaans , Tamil , Finnish , Portuguese , Italian , Spanish , Russian , Polish , Latvian and Modern Greek are languages that do not have phonetic aspirated consonants. Standard Chinese (Mandarin) has stops and affricates distinguished by aspiration: for instance, /t tʰ/ , /t͡s t͡sʰ/ . In pinyin , tenuis stops are written with letters that represent voiced consonants in English, and aspirated stops with letters that represent voiceless consonants. Thus d represents /t/ , and t represents /tʰ/ . Wu Chinese and Southern Min has

288-478: A three-way distinction between voiceless, aspirated, and voiced, such as /t tʰ d/ . Western Armenian has a two-way distinction between aspirated and voiced: /tʰ d/ . Western Armenian aspirated /tʰ/ corresponds to Eastern Armenian aspirated /tʰ/ and voiced /d/ , and Western voiced /d/ corresponds to Eastern voiceless /t/ . Ancient Greek , including the Classical Attic and Koine Greek dialects, had

336-482: A three-way distinction in stops and affricates: /p pʰ b/ . In addition to aspirated and unaspirated consonants, there is a series of muddy consonants , like /b/ . These are pronounced with slack or breathy voice : that is, they are weakly voiced. Muddy consonants as initial cause a syllable to be pronounced with low pitch or light (陽 yáng ) tone . Many Indo-Aryan languages have aspirated stops. Sanskrit , Hindustani , Bengali , Marathi , and Gujarati have

384-612: A three-way distinction in stops like Eastern Armenian: /t tʰ d/ . These series were called ψιλά , δασέα , μέσα ( psilá, daséa, mésa ) "smooth, rough, intermediate", respectively, by Koine Greek grammarians. There were aspirated stops at three places of articulation: labial, coronal, and velar /pʰ tʰ kʰ/ . Earlier Greek, represented by Mycenaean Greek , likely had a labialized velar aspirated stop /kʷʰ/ , which later became labial, coronal, or velar depending on dialect and phonetic environment. The other Ancient Greek dialects, Ionic , Doric , Aeolic , and Arcadocypriot , likely had

432-482: A variety of formats for rendering Greek and Greek shorthand using Latin letters. Examples include "8elo" and "thelw" for θέλω , "3ava" for ξανά , and "yuxi" for ψυχή . Owing to the difficulties encountered in transliterating and transcribing both ancient and modern Greek into the Latin alphabet, a number of regulatory bodies have been established. The Hellenic Organization for Standardization (ELOT), in cooperation with

480-590: A variety of romanizations for names and placenames in the 19th and 20th century. The Hellenic Organization for Standardization (ELOT) issued its system in cooperation with the International Organization for Standardization (ISO) in 1983. This system was adopted (with minor modifications) by the United Nations ' Fifth Conference on the Standardization of Geographical Names at Montreal in 1987, by

528-511: A voiced consonant actually represents a breathy-voiced or murmured consonant, as with the "voiced aspirated" bilabial stop ⟨ bʰ ⟩ in the Indo-Aryan languages . This consonant is therefore more accurately transcribed as ⟨ b̤ ⟩, with the diacritic for breathy voice, or with the modifier letter ⟨ bʱ ⟩, a superscript form of the symbol for the voiced glottal fricative ⟨ ɦ ⟩. Some linguists restrict

576-791: Is also a feature of Scottish Gaelic : Preaspirated stops also occur in most Sami languages . For example, in Northern Sami , the unvoiced stop and affricate phonemes /p/ , /t/ , /ts/ , /tʃ/ , /k/ are pronounced preaspirated ( [ʰp] , [ʰt] [ʰts] , [ʰtʃ] , [ʰk] ) in medial or final position. Although most aspirated obstruents in the world's languages are stops and affricates, aspirated fricatives such as [sʰ] , [ɸʷʰ] and [ɕʰ] have been documented in Korean and Xuanzhou Wu , and [xʰ] has been described for Spanish, though these are allophones of other phonemes. Similarly, aspirated fricatives and even aspirated nasals, approximants, and trills occur in

624-445: Is around 0.5–1.2 billion years old and is spinning with a projected rotational velocity of 57 km/s. It has 1.6 times the mass of the Sun and 1.9 times the Sun's radius . The star is radiating seven times the luminosity of the Sun from its photosphere at an effective temperature of 6,906 K. An infrared excess has been detected at multiple frequencies, indicating that

672-410: Is common to mark the long vowels with macrons over the Latin letters and to leave the short vowels unmarked; such macrons should not be confused or conflated with those used by some systems to mark eta and omega as distinct from epsilon , iota , and omicron . Greece's early Attic numerals were based on a small sample of letters (including heta ) arranged in multiples of 5 and 10, likely forming

720-530: Is drifting further away with a radial velocity of +25 km/s. Based on its motion through space, it appears to be a member of the IC 2391 supercluster. This is an F-type main-sequence star with a stellar classification of F1V. It is a pulsating variable that varies in brightness by less than a tenth of a magnitude owing to nonradial gravity wave oscillations. Four pulsation frequencies have been identified with periods of 17.6, 12.8, 16.3, and 18.2 hours. The star

768-946: Is longer or shorter depending on the language or the place of articulation. Armenian and Cantonese have aspiration that lasts about as long as English aspirated stops, in addition to unaspirated stops. Korean has lightly aspirated stops that fall between the Armenian and Cantonese unaspirated and aspirated stops as well as strongly-aspirated stops whose aspiration lasts longer than that of Armenian or Cantonese. (See voice onset time .) Aspiration varies with place of articulation . The Spanish voiceless stops /p t k/ have voice onset times (VOTs) of about 5, 10, and 30 milliseconds, and English aspirated /p t k/ have VOTs of about 60, 70, and 80 ms. Voice onset time in Korean has been measured at 20, 25, and 50 ms for /p t k/ and 90, 95, and 125 for /pʰ tʰ kʰ/ . When aspirated consonants are doubled or geminated ,

816-422: Is now obsolete. The aspiration modifier letter may be doubled to indicate especially strong or long aspiration. Hence, the two degrees of aspiration in Korean stops are sometimes transcribed ⟨ kʰ kʰʰ ⟩ or ⟨ kʻ ⟩ and ⟨ kʰ ⟩, but they are usually transcribed [k] and [kʰ] , with the details of voice onset time given numerically. Preaspirated consonants are marked by placing

864-477: Is realised as an extended length of the frication. Aspirated consonants are not always followed by vowels or other voiced sounds. For example, in Eastern Armenian , aspiration is contrastive even word-finally, and aspirated consonants occur in consonant clusters . In Wahgi , consonants are aspirated only when they are in final position. The degree of aspiration varies: the voice onset time of aspirated stops

912-673: Is shaped like the Latinate semicolon . Greek punctuation which has been given formal romanizations include: There are many archaic forms and local variants of the Greek alphabet . Beta , for example, might appear as round Β or pointed [REDACTED] throughout Greece but is also found in the forms [REDACTED] (at Gortyn ), [REDACTED] and [REDACTED] ( Thera ), [REDACTED] ( Argos ), [REDACTED] ( Melos ), [REDACTED] ( Corinth ), [REDACTED] ( Megara and Byzantium ), and even [REDACTED] ( Cyclades ). Well into

960-580: The International Organization for Standardization (ISO), released a system in 1983 which has since been formally adopted by the United Nations , the United Kingdom and United States. The following tables list several romanization schemes from the Greek alphabet to modern English. Note, however, that the ELOT, UN, and ISO formats for Modern Greek intend themselves as translingual and may be applied in any language using

1008-525: The Latin alphabet . The American Library Association and Library of Congress romanization scheme employs its "Ancient or Medieval Greek" system for all works and authors up to the Fall of Constantinople in 1453, although Byzantine Greek was pronounced distinctly and some have considered "Modern" Greek to have begun as early as the 12th century. For treatment of polytonic Greek letters —for example, ᾤ —see also

1056-603: The [bʱ], [dʱ], [ɡʱ] that are common among the languages of India , are extremely rare. They have been documented in Kelabit . Aspiration has varying significance in different languages. It is either allophonic or phonemic, and may be analyzed as an underlying consonant cluster. In some languages, stops are distinguished primarily by voicing , and voiceless stops are sometimes aspirated, while voiced stops are usually unaspirated. English voiceless stops are aspirated for most native speakers when they are word-initial or begin

1104-518: The aspiration modifier letter ⟨ ◌ʰ ⟩, a superscript form of the symbol for the voiceless glottal fricative ⟨ h ⟩. For instance, ⟨ p ⟩ represents the voiceless bilabial stop , and ⟨ pʰ ⟩ represents the aspirated bilabial stop. Voiced consonants are seldom actually aspirated. Symbols for voiced consonants followed by ⟨ ◌ʰ ⟩, such as ⟨ bʰ ⟩, typically represent consonants with murmured voiced release (see below ). In

1152-622: The first letter of the pair indicates vowels which should be taken (and romanized) separately. Although the second vowel is not marked with a superfluous diaeresis in Greek, the first-edition ELOT 743 and the UN systems place a diaeresis on the Latin vowel for the sake of clarity. Apart from the diacritical marks native to Greek itself or used to romanize its characters, linguists also regularly mark vowel length with macrons (  ¯  ) marking long vowels and rounded breves (  ˘  ) marking short vowels . Where these are romanized, it

1200-403: The grammatical tradition of Sanskrit , aspirated consonants are called voiceless aspirated , and breathy-voiced consonants are called voiced aspirated . There are no dedicated IPA symbols for degrees of aspiration and typically only two degrees are marked: unaspirated ⟨ k ⟩ and aspirated ⟨ kʰ ⟩. An old symbol for light aspiration was ⟨ ʻ ⟩, but this

1248-512: The section on romanizing Greek diacritical marks below. ELOT approved in 1982 the ELOT 743 standard, revised in 2001, whose Type 2 (Greek: Τύπος 2 , romanized:  Typos 2 ) transcription scheme has been adopted by the Greek and Cypriot governments as standard for romanization of names on Greek and Cypriot passports . It also comprised a Type 1 (Greek: Τύπος 1 , romanized:  Typos 1 ) transliteration table, which

1296-410: The transcriptions of Modern Greek into Latin letters used by ELOT, UN and ISO are essentially equivalent, while there remain minor differences in how they approach reversible transliteration . The American Library Association and Library of Congress romanization scheme employs its "Modern Greek" system for all works and authors following the Fall of Constantinople in 1453. In the table below,

1344-554: The vocal folds open (spread) and not vibrating, and voiced consonants are produced when the vocal folds are fractionally closed and vibrating ( modal voice ). Voiceless aspiration occurs when the vocal folds remain open after a consonant is released. An easy way to measure this is by noting the consonant's voice onset time , as the voicing of a following vowel cannot begin until the vocal folds close. In some languages, such as Navajo , aspiration of stops tends to be phonetically realised as voiceless velar airflow; aspiration of affricates

1392-662: The United Kingdom's Permanent Committee on Geographical Names for British Official Use (PCGN) and by the United States' Board on Geographic Names (BGN) in 1996, and by the ISO itself in 1997. Romanization of names for official purposes (as with passports and identity cards) were required to use the ELOT system within Greece until 2011, when a legal decision permitted Greeks to use irregular forms (such as " Demetrios " for Δημήτριος ) provided that official identification and documents also list

1440-427: The aspiration modifier letter before the consonant symbol: ⟨ ʰp ⟩ represents the preaspirated bilabial stop. Unaspirated or tenuis consonants are occasionally marked with the modifier letter for unaspiration ⟨ ◌˭ ⟩, a superscript equals sign : ⟨ t˭ ⟩. Usually, however, unaspirated consonants are left unmarked: ⟨ t ⟩. Voiceless consonants are produced with

1488-436: The classical Greek alphabet such as heta ( Ͱ & ͱ ), meanwhile, usually take their nearest English equivalent (in this case, h ) but are too uncommon to be listed in formal transliteration schemes. Uncommon Greek letters which have been given formal romanizations include: The sounds of Modern Greek have diverged from both those of Ancient Greek and their descendant letters in English and other languages. This led to

1536-449: The cluster crosses a morpheme boundary or not. For instance, distend has unaspirated [t] since it is not analyzed as two morphemes, but distaste has an aspirated middle [tʰ] because it is analyzed as dis- + taste and the word taste has an aspirated initial t . Word-final voiceless stops are sometimes aspirated. Voiceless stops in Pashto are slightly aspirated prevocalically in

1584-404: The first rather than the second vowel letter, or by having a diaeresis ( ¨ ) over the second letter. For treatment of accents and diaereses —for example, ϊ —also see the section on romanizing Greek diacritical marks below. The traditional polytonic orthography of Greek uses several distinct diacritical marks to render what was originally the pitch accent of Ancient Greek and

1632-590: The inspiration for the later Etruscan and Roman numerals . This early system was replaced by Greek numerals which employed the entire alphabet, including the nonstandard letters digamma , stigma , or sigma-tau (placed between epsilon and zeta), koppa (placed between pi and rho), and sampi (placed after omega). As revised in 2001, ELOT 743 provides for the uncommon characters to be given (in Greek) as $ for stigma, + for koppa, and / for sampi. These symbols are not given lower-case equivalents. When used as numbers,

1680-763: The letters are used in combination with the upper keraia numeral sign ⟨ ʹ ⟩ to denote numbers from 1 to 900 and in combination with the lower keraia ⟨ ͵ ⟩ to denote multiples of 1000. ( For a full table of the signs and their values, see Greek numerals .) These values are traditionally romanized as Roman numerals , so that Αλέξανδρος Γ' ο Μακεδών would be translated as Alexander III of Macedon and transliterated as Aléxandros III o Makedṓn rather than Aléxandros G' or Aléxandros 3 . Greek laws and other official documents of Greece which employ these numerals, however, are to be formally romanized using "decimal" Arabic numerals . Ancient Greek text did not mark word division with spaces or interpuncts , instead running

1728-528: The modern period, classical and medieval Greek was also set using a wide array of ligatures , symbols combining or abbreviating various sets of letters, such as those included in Claude Garamond 's 16th-century grecs du roi . For the most part, such variants—as ϖ and [REDACTED] for π , ϛ for σ τ , and ϗ for και —are just silently emended to their standard forms and transliterated accordingly. Letters with no equivalent in

1776-418: The presence or absence of word-initial /h/ . In 1982, monotonic orthography was officially introduced for modern Greek. The only diacritics that remain are the acute accent (indicating stress) and the diaeresis (indicating that two consecutive vowels should not be combined). When a Greek diphthong is accented, the accent mark is placed over the second letter of the pair. This means that an accent over

1824-614: The same three-way distinction at one point, but Doric seems to have had a fricative in place of /tʰ/ in the Classical period. Later, during the Koine and Medieval Greek periods, the aspirated and voiced stops /tʰ d/ of Attic Greek lenited to voiceless and voiced fricatives, yielding /θ ð/ in Medieval and Modern Greek . Cypriot Greek is notable for aspirating its inherited (and developed across word-boundaries) voiceless geminate stops, yielding

1872-414: The series /pʰː tʰː cʰː kʰː/. The term aspiration sometimes refers to the sound change of debuccalization , in which a consonant is lenited (weakened) to become a glottal stop or fricative [ʔ h ɦ] . So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice , a type of phonation or vibration of the vocal folds . The modifier letter ⟨ ◌ʰ ⟩ after

1920-543: The sound: ⟨th⟩, ⟨ph⟩, ⟨rh⟩, and ⟨ch⟩. Because English orthography has changed so much from the original Greek , modern scholarly transliteration now usually renders ⟨κ⟩ as ⟨k⟩ and the diphthongs ⟨αι, οι, ει, ου⟩ as ⟨ai, oi, ei, ou⟩. " Greeklish " has also spread within Greece itself, owing to the rapid spread of digital telephony from cultures using the Latin alphabet . Since Greek typefaces and fonts are not always supported or robust, Greek email and chatting has adopted

1968-427: The special rules for vowel combinations ( αι, αυ, ει, ευ, ηυ, οι, ου, ωυ ) only apply when these letters function as digraphs . There are also words where the same letters stand side by side incidentally but represent separate vowels. In these cases each of the two letters is transcribed separately according to the normal rules for single letters. Such cases are marked in Greek orthography by either having an accent on

2016-622: The standard forms (as, for example, "Demetrios OR Dimitrios"). Other romanization systems still encountered are the BGN/PCGN's earlier 1962 system and the system employed by the American Library Association and the United States' Library of Congress . Aspirated consonant In the International Phonetic Alphabet (IPA), aspirated consonants are written using the symbols for voiceless consonants followed by

2064-452: The star is being orbited by a pair of debris disks . Romanization of Greek Romanization of Greek is the transliteration ( letter -mapping) or transcription ( sound -mapping) of text from the Greek alphabet into the Latin alphabet . The conventions for writing and romanizing Ancient Greek and Modern Greek differ markedly. The sound of the English letter B ( /b/ )

2112-510: The stop is held longer and then has an aspirated release. An aspirated affricate consists of a stop, fricative, and aspirated release. A doubled aspirated affricate has a longer hold in the stop portion and then has a release consisting of the fricative and aspiration. Icelandic and Faroese have consonants with preaspiration [ʰp ʰt ʰk] , and some scholars interpret them as consonant clusters as well. In Icelandic, preaspirated stops contrast with double stops and single stops : Preaspiration

2160-463: The words together ( scripta continua ). In the Hellenistic period, a variety of symbols arose for punctuation or editorial marking ; such punctuation (or the lack thereof) are variously romanized, inserted, or ignored in different modern editions. Modern Greek punctuation generally follows French with the notable exception of Greek's use of a separate question mark , the erotimatiko , which

2208-601: Was a form of the Cumaean alphabet derived from the Euboean script that valued Χ as / k s / and Η as / h / and used variant forms of Λ and Σ that became L and S . When this script was used to write the classical Greek alphabet, ⟨κ⟩ was replaced with ⟨c⟩, ⟨αι⟩ and ⟨οι⟩ became ⟨æ⟩ and ⟨œ⟩, and ⟨ει⟩ and ⟨ου⟩ were simplified to ⟨i⟩ (more rarely—corresponding to an earlier pronunciation—⟨e⟩) and ⟨u⟩. Aspirated consonants like ⟨θ⟩, ⟨φ⟩, initial-⟨ρ⟩, and ⟨χ⟩ simply wrote out

2256-470: Was extensively modified in the second edition of the standard. International versions of ELOT 743, with an English language standard document, were approved by the UN (V/19, 1987) and the British and American governments. The ISO approved in 1997 its version, ISO 843 , with a different Type 1 transliteration system, which was adopted four years later by ELOT itself, while the U.N. did not update its version. So

2304-720: Was written as β in ancient Greek but is now written as the digraph μπ , while the modern β sounds like the English letter V ( /v/ ) instead. The Greek name Ἰωάννης became Johannes in Latin and then John in English, but in modern Greek has become Γιάννης ; this might be written as Yannis , Jani, Ioannis, Yiannis, or Giannis, but not Giannes or Giannēs as it would be for ancient Greek. The word Άγιος might variously appear as Hagiοs, Agios, Aghios, or Ayios, or simply be translated as " Holy " or " Saint " in English forms of Greek placenames . Traditional English renderings of Greek names originated from Roman systems established in antiquity. The Roman alphabet itself
