À

À, à (a-grave) is a letter of the Catalan, Emilian-Romagnol, French, Italian, Maltese,  Occitan, Portuguese, Sardinian, Scottish Gaelic, Vietnamese, and Welsh languages consisting of the letter A of the ISO basic Latin alphabet and a grave accent. À is also used in Pinyin transliteration. In most languages, it represents the vowel a. This letter is also a letter in Taos to indicate a mid tone.

In accounting or invoices, à abbreviates "at a rate of": "5 apples à $1" (one dollar each). That usage is based upon the French preposition à and has evolved into the at sign (@). Sometimes, it is part of a surname: Thomas à Kempis, Mary Anne à Beckett.

Emilian-Romagnol
À is used in Emilian to represent short stressed [a], e.g. Bolognese dialect sacàtt [saˈkatː] "sack".

French
The grave accent is used in the French language to differentiate homophones, e.g. the.F.SG and  there.

Portuguese
À is used in Portuguese to represent a contraction of the feminine singular definite article A with the preposition A:
 * Ele foi à praia.
 * He went to the beach.

Scottish Gaelic
In early orthographic descriptions of Scottish Gaelic from the 18th and 19th centuries, à is the only way to represent a long [a]; later forms of Scottish Gaelic also used the acute accent [á] to indicate a longer [a] sound.
