67-514: O , or o , is the fifteenth letter and the fourth vowel letter of the Latin alphabet , used in the modern English alphabet , the alphabets of other western European languages and others worldwide. Its name in English is o (pronounced / ˈ oʊ / ), plural oes . In English, the name of the letter is the "long O" sound, pronounced / ˈ oʊ / . In most other languages, its name matches
134-411: A multigraph . Multigraphs include digraphs of two letters (e.g. English ch , sh , th ), and trigraphs of three letters (e.g. English tch ). The same letterform may be used in different alphabets while representing different phonemic categories. The Latin H , Greek eta ⟨Η⟩ , and Cyrillic en ⟨Н⟩ are homoglyphs , but represent different phonemes. Conversely,
201-513: A lowercase form (also called minuscule ). Upper- and lowercase letters represent the same sound, but serve different functions in writing. Capital letters are most often used at the beginning of a sentence, as the first letter of a proper name or title, or in headers or inscriptions. They may also serve other functions, such as in the German language where all nouns begin with capital letters. The terms uppercase and lowercase originated in
268-483: A pitch trace on a musical scale . Beyond the letters themselves, there are a variety of secondary symbols which aid in transcription. Diacritic marks can be combined with the letters to add tone and phonetic detail such as secondary articulation . There are also special symbols for prosodic features such as stress and intonation. There are two principal types of brackets used to set off (delimit) IPA transcriptions: Less common conventions include: All three of
335-549: A variety of modern uses in mathematics, science, and engineering . People and objects are sometimes named after letters, for one of these reasons: The word letter entered Middle English c. 1200 , borrowed from the Old French letre . It eventually displaced the previous Old English term bōcstæf ' bookstaff '. Letter ultimately descends from the Latin littera , which may have been derived from
402-532: A conflicting use to delimit prosodic transcription within the Voice Quality Symbols , which are an extension of IPA used in extIPA, but are not otherwise used in IPA proper. Other delimiters sometimes seen are pipes and double pipes taken from Americanist phonetic notation . However, these conflict with the pipes used in basic IPA prosodic transcription. Other delimiters are double slashes, –
469-580: A group of French and English language teachers, led by the French linguist Paul Passy , formed what would be known from 1897 onwards as the International Phonetic Association (in French, l'Association phonétique internationale ). The idea of the alphabet had been suggested to Passy by Otto Jespersen . It was developed by Passy along with other members of the association, principally Daniel Jones . The original IPA alphabet

Authors who employ such nonstandard use are encouraged to include a chart or other explanation of their choices, which is good practice in general, as linguists differ in their understanding of the exact meaning of IPA symbols and common conventions change over time. Many British dictionaries, including
603-695: A row left out to save space. In the table below, a slightly different arrangement is made: All pulmonic consonants are included in the pulmonic-consonant table, and the vibrants and laterals are separated out so that the rows reflect the common lenition pathway of stop → fricative → approximant , as well as the fact that several letters pull double duty as both fricative and approximant; affricates may then be created by joining stops and fricatives from adjacent cells. Shaded cells represent articulations that are judged to be impossible or not distinctive. Vowel letters are also grouped in pairs—of unrounded and rounded vowel sounds—with these pairs also arranged from front on

Opera librettos are authoritatively transcribed in IPA, such as Nico Castel 's volumes and Timothy Cheek's book Singing in Czech . Opera singers' ability to read IPA was used by the site Visual Thesaurus , which employed several opera singers "to make recordings for
737-674: Is a word, also spelled "oh" and pronounced /oʊ/ . Before a noun, usually capitalized, it indicates direct address (the vocative case ), as in the titles " O Canada " or " O Captain! My Captain! " or in certain verses of the Bible . ⟨o⟩ is commonly associated with the open-mid back rounded vowel [ɔ] , mid back rounded vowel [o̞] or close-mid back rounded vowel [o] in many languages. Other languages use ⟨o⟩ for various values, usually back vowels which are at least partly open. Derived letters such as ⟨ ö ⟩ and ⟨ ø ⟩ have been created for

In most dialects of British English , it is either an open-mid back rounded vowel [ɔ] or an open back rounded vowel [ɒ] ; in American English , it is most commonly an unrounded back [ɑ] to a central vowel [a] . Common digraphs include ⟨oo⟩ , which represents either / uː / or / ʊ / ; ⟨oi⟩ or ⟨oy⟩ , which typically represents
871-442: Is an alphabetic system of phonetic notation based primarily on the Latin script . It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech . The IPA is used by lexicographers , foreign language students and teachers, linguists , speech–language pathologists , singers, actors, constructed language creators, and translators . The IPA

In computer systems, each has its own code point , U+006E n LATIN SMALL LETTER N and U+00F1 ñ LATIN SMALL LETTER N WITH TILDE , respectively. Letters may also function as numerals with assigned numerical values, for example with Roman numerals . Greek and Latin letters have

A few letters that did not indicate specific sounds have been retired (⟨ ˇ ⟩, once used for the "compound" tone of Swedish and Norwegian, and ⟨ ƞ ⟩, once used for the moraic nasal of Japanese), though one remains: ⟨ ɧ ⟩, used for the sj-sound of Swedish. When

To represent additional qualities of speech—such as tooth gnashing , lisping , and sounds made with a cleft palate —an extended set of symbols may be used. Segments are transcribed by one or more IPA symbols of two basic types: letters and diacritics . For example,

Double angle brackets may occasionally be useful to distinguish original orthography from transliteration, or the idiosyncratic spelling of a manuscript from the normalized orthography of the language. Pipes are sometimes used instead of double angle brackets to denote the distinct allographs of a grapheme that are known as glyphs . For example, print | g | and script | ɡ | are two glyph variants of

A letter is a type of grapheme , the smallest functional unit within a writing system. Letters are graphemes that broadly correspond to phonemes , the smallest functional units of sound in speech. Similarly to how phonemes are combined to form spoken words, letters may be combined to form written words. A single phoneme may also be represented by multiple letters in sequence, collectively called
1407-427: Is the official chart as posted at the website of the IPA. The letters chosen for the IPA are meant to harmonize with the Latin alphabet . For this reason, most letters are either Latin or Greek , or modifications thereof. Some letters are neither: for example, the letter denoting the glottal stop , ⟨ ʔ ⟩, originally had the form of a question mark with the dot removed. A few letters, such as that of

A braille representation of the IPA for blind or visually impaired professionals and students has also been developed. The International Phonetic Alphabet is occasionally modified by the Association. After each modification, the Association provides an updated simplified presentation of the alphabet in
1541-460: The Hebrew alphabet for transcription of foreign words. Bilingual dictionaries that translate from foreign languages into Russian usually employ the IPA, but monolingual Russian dictionaries occasionally use pronunciation respelling for foreign words. The IPA is more common in bilingual dictionaries, but there are exceptions here too. Mass-market bilingual Czech dictionaries, for instance, tend to use
1608-570: The IPA extensions . In the IPA itself, however, only lower-case letters are used. The 1949 edition of the IPA handbook indicated that an asterisk ⟨*⟩ might be prefixed to indicate that a word was a proper name, but this convention was not included in the 1999 Handbook , which notes the contrary use of the asterisk as a placeholder for a sound or feature that does not have a symbol. The IPA has widespread use among classical singers during preparation as they are frequently required to sing in
1675-792: The Oxford English Dictionary and some learner's dictionaries such as the Oxford Advanced Learner's Dictionary and the Cambridge Advanced Learner's Dictionary , now use the International Phonetic Alphabet to represent the pronunciation of words. However, most American (and some British) volumes use one of a variety of pronunciation respelling systems, intended to be more comfortable for readers of English and to be more acceptable across dialects, without
1742-562: The voiced pharyngeal fricative , ⟨ ʕ ⟩, were inspired by other writing systems (in this case, the Arabic letter ⟨ ﻉ ⟩, ʿayn , via the reversed apostrophe). Some letter forms derive from existing letters: The International Phonetic Alphabet is based on the Latin script , and uses as few non-Latin letters as possible. The Association created the IPA so that the sound values of most letters would correspond to "international usage" (approximately Classical Latin ). Hence,

The International Phonetic Association organizes the letters of the IPA into three categories: pulmonic consonants, non-pulmonic consonants, and vowels. Pulmonic consonant letters are arranged singly or in pairs of voiceless ( tenuis ) and voiced sounds, with these then grouped in columns from front (labial) sounds on
1876-645: The Greek diphthera 'writing tablet' via Etruscan . Until the 19th century, letter was also used interchangeably to refer to a speech segment . Before alphabets, phonograms , graphic symbols of sounds, were used. There were three kinds of phonograms: verbal, pictures for entire words, syllabic, which stood for articulations of words, and alphabetic, which represented signs or letters. The earliest examples of which are from Ancient Egypt and Ancient China, dating to c. 3000 BCE . The first consonantal alphabet emerged around c. 1800 BCE , representing
1943-681: The Greek alphabet, though their sound values may differ from Greek. For most Greek letters, subtly different glyph shapes have been devised for the IPA, specifically ⟨ ɑ ⟩, ⟨ ꞵ ⟩, ⟨ ɣ ⟩, ⟨ ɛ ⟩, ⟨ ɸ ⟩, ⟨ ꭓ ⟩ and ⟨ ʋ ⟩, which are encoded in Unicode separately from their parent Greek letters. One, however – ⟨ θ ⟩ – has only its Greek form, while for ⟨ ꞵ ~ β ⟩ and ⟨ ꭓ ~ χ ⟩, both Greek and Latin forms are in common use. The tone letters are not derived from an alphabet, but from
2010-467: The IPA Handbook , the letters ⟨ c ⟩ and ⟨ ɟ ⟩ are used for /t͡ʃ/ and /d͡ʒ/ . Among the symbols of the IPA, 107 letters represent consonants and vowels , 31 diacritics are used to modify these, and 17 additional signs indicate suprasegmental qualities such as length , tone , stress , and intonation . These are organized into a chart; the chart displayed here
2077-579: The IPA have consisted largely of renaming symbols and categories and in modifying typefaces . Extensions to the International Phonetic Alphabet for speech pathology (extIPA) were created in 1990 and were officially adopted by the International Clinical Phonetics and Linguistics Association in 1994. They were substantially revised in 2015. The general principle of the IPA is to provide one letter for each distinctive sound ( speech segment ). This means that: The alphabet

2144-412: The IPA is used for broad phonetic or for phonemic transcription, the letter–sound correspondence can be rather loose. The IPA has recommended that more 'familiar' letters be used when that would not cause ambiguity. For example, ⟨ e ⟩ and ⟨ o ⟩ for [ɛ] and [ɔ] , ⟨ t ⟩ for [t̪] or [ʈ] , ⟨ f ⟩ for [ɸ] , etc. Indeed, in the illustration of Hindi in

IPA letters have been incorporated into the alphabets of various languages, notably via the Africa Alphabet in many sub-Saharan languages such as Hausa , Fula , Akan , Gbe languages , Manding languages , Lingala , etc. Capital case variants have been created for use in these languages. For example, Kabiyè of northern Togo has Ɖ ɖ , Ŋ ŋ , Ɣ ɣ , Ɔ ɔ , Ɛ ɛ , Ʋ ʋ . These, and others, are supported by Unicode , but appear in Latin ranges other than
2278-537: The IPA remained nearly static until the Kiel Convention in 1989, which substantially revamped the alphabet. A smaller revision took place in 1993 with the resurrection of letters for mid central vowels and the retirement of letters for voiceless implosives . The alphabet was last revised in May 2005 with the addition of a letter for a labiodental flap . Apart from the addition and removal of symbols, changes to
2345-532: The IPA.) Of more than 160 IPA symbols, relatively few will be used to transcribe speech in any one language, with various levels of precision. A precise phonetic transcription, in which sounds are specified in detail, is known as a narrow transcription . A coarser transcription with less detail is called a broad transcription. Both are relative terms, and both are generally enclosed in square brackets. Broad phonetic transcriptions may restrict themselves to easily heard details, or only to details that are relevant to
2412-499: The International Phonetic Association. As of the most recent change in 2005, there are 107 segmental letters, an indefinitely large number of suprasegmental letters, 44 diacritics (not counting composites), and four extra-lexical prosodic marks in the IPA. These are illustrated in the current IPA chart , posted below in this article and on the International Phonetic Association's website. In 1886,

From there, the most widely used alphabet today emerged, Latin, which is written and read from left to right. The Phoenician alphabet had 22 letters, nineteen of which the Latin alphabet used, and the Greek alphabet, adapted c. 900 BCE , added four letters to those used in Phoenician. This Greek alphabet

Capital letters were stored in a higher drawer or upper case. In most alphabetic scripts, diacritics (or accents) are a routinely used.

For example, the English word little may be transcribed broadly as [ˈlɪtəl] , approximately describing many pronunciations. A narrower transcription may focus on individual or dialectical details: [ˈɫɪɾɫ] in General American , [ˈlɪʔo] in Cockney , or [ˈɫɪːɫ] in Southern US English . Phonemic transcriptions, which express

Letters are associated with specific names, which may differ between languages and dialects. Z , for example, is usually called zed outside of the United States, where it is named zee . Both ultimately derive from the name of the parent Greek letter zeta ⟨Ζ⟩ . In alphabets, letters are arranged in alphabetical order , which also may vary by language. In Spanish, ⟨ñ⟩

Some examples of contrasting brackets in the literature: In some English accents, the phoneme /l/ , which is usually spelled as ⟨l⟩ or ⟨ll⟩ , is articulated as two distinct allophones: the clear [l] occurs before vowels and the consonant /j/ , whereas the dark [ɫ] / [lˠ] occurs before consonants, except /j/ , and at

For example, the respelling systems in many American dictionaries (such as Merriam-Webster ) use ⟨y⟩ for IPA [ j] and ⟨sh⟩ for IPA [ ʃ ] , reflecting the usual spelling of those sounds in English. (In IPA, [y] represents the sound of the French ⟨u⟩ , as in tu , and [sh] represents

Minor changes were made such as the removal of certain letters, such as thorn ⟨Þ þ⟩ , wynn ⟨Ƿ ƿ⟩ , and eth ⟨Ð ð⟩ . A letter can have multiple variants, or allographs , related to variation in style of handwriting or printing .

3618-428: The letter's pronunciation in open syllables . Its graphic form has remained fairly constant from Phoenician times until today. The name of the Phoenician letter was ʿeyn , meaning "eye", and its shape originates simply as a drawing of a human eye (possibly inspired by the corresponding Egyptian hieroglyph , cf. Proto-Sinaitic script ). Its original sound value was that of a consonant, probably [ ʕ ] ,
3685-408: The lungs. Pulmonic consonants make up the majority of consonants in the IPA, as well as in human language. All consonants in English fall into this category.

The procedure for modifying

For example, ⟨ cot ⟩ would be used for the orthography of the English word cot , as opposed to its pronunciation /ˈkɒt/ .

However, italics are sometimes ambiguous, and italic markup

Like the other English vowel letters, it has associated "long" and "short" pronunciations. The "long" ⟨o⟩ as in boat is actually most often a diphthong / oʊ / (realized dialectically anywhere from [o] to [əʊ] ). In English, there

Slashes are used to signal phonemic transcription ; therefore, /tʃ/ is more abstract than either [t̠̺͡ʃʰ] or [c] and might refer to either, depending on the context and language. Occasionally, letters or diacritics are added, removed, or modified by

The use of this Phoenician letter for a vowel sound is due to the early Greek alphabets , which adopted the letter " omicron " to represent the vowel /o/ .
