In
linguistics,
vowel length is the perceived
duration of a
vowel sound. Often the
chroneme, or the "longness", acts like a consonant, and may etymologically be one, such as in Australian English. While not distinctive in most dialects of
English, vowel length is an important
phonemic factor in many other languages, for instance in
Finnish,
Fijian,
Japanese,
Old English,
and
Vietnamese. It plays a phonetic role in the majority of dialects of
English English, and is said to be phonemic in a few other dialects, such as
Australian English and
New Zealand English. It also plays a lesser phonetic role in
Cantonese, which is exceptional among the
spoken variants of
Chinese.
Many languages do not distinguish vowel length, and those that do usually distinguish between short vowels and long vowels. There are very few languages that distinguish three vowel lengths, for instance Luiseño. Some languages, such as Finnish, Estonian and Japanese, also have words where long vowels are immediately followed by more vowels, e.g. Japanese ''hōō'' "phoenix" or Estonian ''jäääär'' "ice edge".
Vowel length and related features
Stress is often reinforced by allophonic vowel length, especially when it is lexical. For example,
French long vowels always occur on stressed syllables.
Finnish, a language with two phonemic lengths, indicates the stress by adding allophonic length. This gives four distinctive lengths and five physical lengths: short and long stressed vowels, short and long unstressed vowels, and a half-long vowel, which is a short vowel found in a syllable immediately preceded by a stressed short vowel, e.g. ''i-s
o''.
Among the languages that have distinctive vowel length, there are some where it may only occur in stressed syllables, e.g. in the Alemannic German dialect and Egyptian Arabic. In languages such as Czech, Finnish or Classical Latin, vowel length is distinctive in unstressed syllables as well.
In some languages, vowel length is sometimes better analyzed as a sequence of two identical vowels. In Finnic languages, such as Finnish, the simplest example follows from consonant gradation: ''haka → haan''. In some cases, it is caused by a following chroneme, which is etymologically a consonant, e.g. ''jää'' " ← Proto-Uralic *''jäŋe''. In noninitial syllables, it is ambiguous if long vowels are vowel clusters — poems written in the Kalevala meter often syllabicate between the vowels, and an (etymologically original) intervocalic ''-h-'' is seen in this and some modern dialects (e.g. ''taivaan'' vs. ''taivahan'' "of the sky"). Morphological treatment of diphthongs is essentially similar to long vowels. Interestingly, some old Finnish long vowels have developed into diphthongs, but successive layers of borrowing have introduced the same long vowels again, such that the diphthong and the long vowel again contrast (e.g. ''nuotti'' "musical note" vs. ''nootti'' "diplomatic note").
In Japanese, most long vowels are the results of the phonetic change of diphthongs; ''au'' and ''ou'' became ''ō'', ''iu'' became ''yū'', ''eu'' became ''yō'', and now ''ei'' is becoming ''ē''. The change occurred after the loss of intervocalic phoneme /h/. For example, modern ''kyōto'' (Kyoto) exhibits the following changes: kyauto → kyoːto. Another example is ''shōnen'' (''boy''): seunen → syoːnen (shoːnen).
Phonemic vowel length
Many languages make a
phonemic distinction between long and short vowels:
Sanskrit,
Japanese,
Finnish,
Hungarian,
Kannada etc.
Long vowels may or may not be separate phonemes. In Latin and Hungarian, long vowels are separate phonemes from short vowels, thus doubling the number of vowel phonemes.

Estonian has three distinctive lengths, but the third is suprasegmental, as it has developed from the allophonic variation caused by now-deleted grammatical markers. For example, half-long 'aa' in ''saada'' comes from the agglutination *''saata+ka'' "send+(imperative)", and the overlong 'aa' in ''saada'' comes from *''saa+ta'' "get+(infinitive)". One of the very few languages to have three lengths, independent of vowel quality or syllable structure, is Mixe. An example from Mixe is "guava", "spider", "knot". Similar claims have been made for Yavapai and Wichita.
Four-way distinctions have been claimed, but these are actually long-short distinctions on adjacent syllables. For example, in kiKamba, there is , , , "hit", "dry", "bite", "we have chosen for everyone and are still choosing".
Long vowels in English
Vowel length (i.e., "long" and "short"), when applied to English, has several different related meanings.
Traditional long and short vowels in English orthography
Traditionally, the vowels (as in ''b
ait b
eet b
ite b
oat b
eauty'') are said to be the "long" counterparts of the vowels (as in ''b
at b
et b
it b
ot b
ut'') which are said to be "short". This terminology reflects their pronunciation before the
Great Vowel Shift.
Traditional English phonics teaching, at the preschool to first grade level, often used the term "long vowel" for any pronunciation that might result from the addition of a silent E (e.g., like) or other vowel letter as follows:
{| class=wikitable
! Letter !! "Short" !! "Long" !! Example
|- align=center
! A a
| || || "mat" / "mate"
|- align=center
! E e
| || || "pet" / "Pete"
|- align=center
! I i
| || || "twin" / "twine"
|- align=center
! O o
| || || "not" / "note"
|- align=center
! U u
| || || "cub" / "cube"
|}
A mnemonic was that each vowel's long sound was its name.
In Middle English, the long vowels were generally written ''i..e, e..e, ea, a..e, o..e, oo, u..e.'' With the Great Vowel Shift, they came to be pronounced . Because ''ea'' and ''oo'' are digraphs, they are not called long vowels today. Under French influence, the letter ''u'' was replaced with ''ou'' (or final ''ow),'' so it is no longer considered a long vowel either. Thus the so-called "long vowels" of Modern English are those vowels written with the help of a silent ''e.''
Allophonic vowel length
In certain dialects of the modern English language, for instance
General American and, to some extent, British
Received Pronunciation, there is
allophonic vowel length: vowel phonemes are realized as longer vowel allophones before voiced
consonant phonemes in the coda of a
syllable. For example, the vowel phoneme in ‘bat’ is realized as a short allophone in , because the phoneme is unvoiced, while the same vowel phoneme in ‘bad’ is realized as a slightly long allophone (which could be transcribed as ), because is voiced. (Incidentally, the final consonant allophones in these syllables also have different relative lengths; the of ''ba
t'' is longer than the of ''ba
d.'')
Symbolic representation of the two allophonic rules:
{| style="margin-left: 1em;"
| || → || ||
|-
| || → ||
|-
| || → || ||
|-
| || → ||
|}
In addition, the vowels of Received Pronunciation are commonly divided into short and long, as obvious from their transcription. The short vowels are (as in ''kit''), (as in ''foot''), (as in ''dress''), (as in ''strut''), (as in ''trap''), (as in ''lot''), and (as in the first syllable of ''ago'' and in the second of ''sofa''). The long vowels are (as in ''fleece''), (as in ''goose''), (as in ''nurse''), as in ''north'' and ''thought'', and (as in ''father'' and ''start''). While a different degree of length is indeed present, there are also differences in the ''quality'' (lax vs tense) of these vowels, and the currently prevalent view tends to emphasise the latter rather than the former.
Contrastive vowel length
In
Australian English, there is contrastive vowel length in closed syllables between long and short and sometimes . The following can be
minimal pairs of length for many speakers:
{| style="margin-left: 1em;" cellspacing="3"
|-
| ''bid'' || vs || as in ''beard''
|-
| ''ferry'' || vs || ''fairy''
|-
| ''can'' meaning ''able to'' || vs || as in ''tin can''
|-
| ''cut'' || vs || ''cart''
|}
Origin
The long vowel may often be traced to
assimilation. In Australian English, the second element of a diphthong has assimilated to the preceding vowel, giving the pronunciation of ''bared'' as , creating a contrast with ''bed'' . Another etymology is the
vocalization of a fricative such as the
voiced velar fricative or
voiced palatal fricative, e.g. Finnish
illative case, or even an approximant, as the English 'r'.
Estonian, of Finnic languages, exhibits a rare phenomenon, where allophonic length variation becomes phonemic following the deletion of the suffixes causing the allophony. Estonian already distinguishes two vowel lengths, but a third one has been introduced by this phenomenon. For example, the Finnic imperative marker *''-k'' caused the preceding vowels to be articulated shorter, and following the deletion of the marker, the allophonic length became phonemic, as shown in the example below. Similarly, the Australian English phoneme was created by the incomplete application of a rule extending before certain voiced consonants, a phenomenon known as the bad-lad split.
Many long vowels in the Indo-European languages were formed from short vowels and one of the laryngeal sounds, conventionally written h1, h2 and h3. If a laryngeal followed a vowel in Proto-Indo-European, it was usually lost in its later descendants and the preceding vowel became long. However, Proto-Indo-European itself already possessed long vowels as well, usually as the result of older sound changes such as Szemerényi's law and Stang's law.
Notations in the Latin alphabet
IPA
In the
International Phonetic Alphabet the sign (not a colon, but two triangles facing each other in an
hourglass shape; Unicode ) is used for both vowel and consonant length. This may be doubled for an extra-long sound, or the top half () used to indicate a sound is "half long". A
breve is used to mark a short vowel or consonant.
Estonian has a three-way phonemic contrast:
:''saada'' "to get"
:''saada'' "send!"
:''sada'' "hundred"
Although not phonemic, the distinction can also be illustrated in certain accents of English:
:''bead''
:''beat''
:''bid''
:''bit''
Diacritics
Macron (ā), used to indicate a long vowel in Maori, Latvian and many transcription schemes, including romanizations for Sanskrit and Arabic, the Hepburn romanization for Japanese, and Yale for Korean. While not part of their standard orthography, the macron is also used as a teaching aid in modern Latin and Ancient Greek textbooks.
* Breves (ă) are used to mark short vowels in several linguistic transcription systems, as well as in Vietnamese.
Acute accent (á), used to indicate a long vowel in Czech, Slovak, Old Norse, Hungarian and Irish.
Circumflex (â), used for example in Welsh. The circumflex is occasionally used as a surrogate for the macrons, particularly in the Kunrei-shiki romanization of Japanese.
Grave accent (à) is used in Scottish Gaelic.
Ogonek (ą), used in Lithuanian to indicate long vowels.
Umlaut mark (ä), used in Aymara to indicate long vowels.
Additional letters
Vowel doubling, used consistently in
Estonian,
Finnish,
Lombard and in closed syllables in
Dutch. Example: Finnish ''tuuli'' 'wind' vs. ''tuli'' 'fire'.
* Estonian also has a rare "overlong" vowel length, but does not distinguish this from the normal long vowel in writing; see the example below.
Consonant doubling after short vowels is very common in Swedish and other Germanic languages, including English. The system is somewhat inconsistent, especially in loan-words, around consonant clusters and with word final nasal consonants. Examples:
:
Consistent use: ''byta'' 'to change' vs ''bytta'' 'tub' and ''koma'' 'coma' vs ''komma'' 'to come'
:
Inconsistent use: ''fält'' 'a field' and ''kam'' 'a comb' (but the verb 'to comb' is ''kamma'')
Classical Milanese orthography uses consonant doubling in closed short syllables, e.g., ''lenguagg'' 'language' and ''pubblegh'' 'public'.
''ie'' is used to mark the long sound in
German. This is due to the preservation and generalization of a historical ''ie'' spelling that originally represented the sound . In northern German, a following ''e'' letter lengthens other vowels as well, e.g., in the name
Kues .
A following ''h'' is frequently used in German and older Swedish spelling, e.g., German ''Zahn'' [tsaːn] 'tooth'.
In Czech, the additional letter ů is used for the long U sound, where the character is known as a kroužek, e.g., ''kůň'' "horse". (This actually developed from the ligature "uo", which signified the diphthong /uo/, which later shifted to /uː/.)
Other signs
Apostrophe, used in Mi'kmaq, as evidenced by the name itself. This is the convention of the Listuguj orthography (Mi'gmaq), and a common substitution for the official acute accent (Míkmaq) of the Francis-Smith orthography.
Colon (punctuation), commonly used as an approximation of the IPA phonetic transcription, and in a few orthographies based on the IPA.
Interpunct, commonly used in non-IPA phonetic transcription, such as the
Americanist system developed by linguists for transcribing the indigenous languages of the Americas. Example: Americanist = IPA .
No distinction
Some languages make no distinction in writing. This is particularly the case with ancient languages such as
Latin and
Old English. Modern edited texts often use macrons with long vowels, however.
Australian English does not distinguish the vowels from in spelling, with words like ‘span’ or ‘can’ having different pronunciations depending on meaning.
Notations in other writing systems
In non-Latin writing systems, a variety of mechanisms have also evolved.
In abjads derived from the Aramaic alphabet, notably Arabic and Hebrew, long vowels are written with consonant letters (mostly approximant consonant letters) in a process called ''mater lectionis'', while short vowels are typically omitted entirely. Most of these scripts also have optional diacritics that can be used to mark short vowels when needed.
In South-Asian abugidas, such as Devanagari or the Thai alphabet, there are different vowel signs for short and long vowels.
In the Japanese
hiragana syllabary, long vowels are usually indicated by adding a vowel character after. For vowels , , and , the corresponding independent vowel is added. Thus: (a), , "okaasan", mother; (i), にいがた "Niigata", city in northern Japan (usu. , in
kanji); (u), "ryuu" (usu. ), dragon. The mid-vowels and may be written with (e) (rare) ( (), neesan, "elder sister") and (o) [ (usu ), ookii, big] , or with (i) ( (), "meirei", command/order) and (u) ( (), ousama, "king") depending on etymological, morphological, and historic grounds.
Most long vowels in the katakana syllabary are written with a special bar symbol (vertical in vertical writing), called a chōon, as in ''mēkā'' "maker" instead of ''meka'' "mecha". However, some long vowels are written with additional vowel characters, as with hiragana, with the distinction being orthographically significant.
In the
Korean Hangul alphabet, vowel length is not distinguished in normal writing. Some dictionaries use a double dot, , for example “
Daikon radish”.
