Ã

Ã/ã (a-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, [ɐ] (its exact height varies from near-open to mid according to dialect). The combination ⟨ãe⟩ represents the diphthong [ɐ̃ĩ̯] in most dialects ([ɐ̃ɪ̯̃] in Brazil's RS, SC, PR, SP, MS and among caipira speakers), and ⟨ão⟩ represents [ɐ̃ũ̯] in most dialects ([ɐ̃ʊ̯̃] in Brazil's RS, SC, PR, SP, MS and among caipira speakers, while in hinterland European northern dialects of Portuguese it represents [aŋ] and in some reintegrationist Galician orthographies it may represent [oŋ]).

The symbol is used for a similar sound in Aromanian, 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 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.

It is often produced by text encoding errors.
