Ã

Ã/ã (a with tilde) is a letter used in some languages, generally considered a variant of the letter A.

In Portuguese, Ã/ã represents a nasal near-open central vowel, [ɐ̃] (its exact height varies from near-open to mid according to dialect). It appears on its own and as part of the diphthongs ãe [ɐ̃j̃] and ão [ɐ̃w̃].

The symbol is used for the nasal vowel /ã/ in Guaraní, Kashubian and Taa.

In Aromanian, the symbol is used for the mid-central vowel /ə/.

In Vietnamese, it represents [aː] in a high breaking-rising tone. This sound is also used in !Xóõ.

In the International Phonetic Alphabet, /ã/ stands for a nasal open front unrounded vowel, as in Quebec French maman and Jean.

The letter was also used in the Greenlandic alphabet to represent a long vowel ([aː]) next to a geminated consonant, but now it is replaced with Aa (example: Ãpilátoq → Aappilattoq).
