Â, â (a-circumflex) is a letter of the French, Friulian, Frisian, Portuguese, Romanian, Turkish, Vietnamese, Walloon, and Welsh alphabets.
Usage in various languages
Berber languages
"â" can be used in Berber Latin alphabet to represent [ʕ].
Croatian, Serbian
"â" is not a letter in the Croatian, Serbian, but simply an "a" with the circumflex. It is used only occasionally, in order to disambiguate homographs which differ only by length of the vowel. Such situation is most common in (but not exclusive to) the plural genitive case, thus the name "genitive sign" for the circumflex and is pronounced as a long vowel. For example, "Ja sam sâm" (Template:Lang-en)
Faroese
Johan Henrik Schrøter, who translated the Gospel of Matthew into Faroese in 1823, used â to denote a non-syllabic a, as in the following example:
| Schrøter 1817 | Modern Faroese |
|---|---|
| Brinhlid situr uj gjiltan Stouli, Teâ hit veâna Vujv, Drevur hoon Sjúra eâv Nordlondun Uj Hildarhaj tiil sujn. |
Brynhild situr í gyltum stóli, tað hitt væna vív, dregur hon Sjúrða av Norðlondum í Hildarheið til sín. |
 is not used in modern Faroese, however.
French
 in the French language is used as the letter "a" with a circumflex accent. It is a remnant of old French, where a vowel was followed, with some exceptions, by the consonant "s". For example, the modern form bâton (Template:Lang-en) comes from the ancient French baston. Phonetically, "â" is pronounced as /ɑ/, but only in dialects that distinguish it from /a/.
Friulian
 is used to represent the /ɑː/ sound.
Romanian
 is the 3rd letter of the Romanian alphabet and represents /ɨ/. This sound is also represented in Romanian as letter î. The difference between the two is that â is used in the middle of the word, as in "România", while î is used at the ends: "înțelegere" (understanding), "a urî" (to hate). A compound word starting or ending with the letter î will retain it, even if it goes in the middle of the word: "neînțelegere" (miss-understanding)
Vietnamese
 is the 3rd letter of the Vietnamese alphabet and represents /ɜ/. In Vietnamese phonology, diacritics can be added to form the following five forms to represent five tones of â.
- Ầ ầ
- Ẩ ẩ
- Ẫ ẫ
- Ấ ấ
- Ậ ậ
Turkish
 is used to indicate the consonant before "a" is palatalised, as in "kâğıt" (paper). It is also used to indicate /aː/ in words where the long vowel changes the meaning, as in "adet" (pieces) and "âdet" (tradition).
Ukrainian
 is used in the ISO 9:1995 system of Ukrainian transliteration as the letter Я.
Portuguese
In Portuguese, â is used to mark a stressed /ɐ/ in words whose stressed syllable is in an unpredictable location within the word, as in "lâmina" (blade) and "râguebi" (rugby). Where the location of the stressed syllable is predictable, the circumflex accent is not used. Â /ɐ/ contrasts with á, pronounced /a/.
Welsh
In Welsh, â is used to represent long stressed a [aː] when, without the circumflex, the vowel would be pronounced as short [a], e.g., âr [aːr] "arable", as opposed to ar [ar] "on", or gwâr [ɡwaːr] "civilised, humane", rather than gwar [ɡwar] "nape of the neck". It is often found in final syllables when two occurrences of the letter a combine to produce one long stressed vowel. This commonly happens when a verb stem ending in stressed a combines with the nominalising suffix -ad, as in cantiata- + -ad giving caniatâd [kanjaˈtaːd] "permission" and also when a singular noun ending in a receives the plural suffix -au, e.g., drama + -au becoming dramâu [draˈmaɨ, draˈmai] "dramas, plays". It is also useful in writing borrowed words with final stress, e.g. brigâd [brɪˈɡaːd] "brigade".
A circumflex is also used in the word â, which is both a preposition meaning "with, by means of, as", and also the third person non-past singular of the verbal noun mynd "go". This distinguishes it in writing from similarly pronounced a "and; whether; who, which, that".
