A mark (´) used to indicate a) the quality or length of a vowel as in French idée b) primary stress, as in Spanish olé c) any stress on a spoken sound or syllable, as in the scanning of a verse.

Acute is also an accent put over vowels in the French language. It looks like the slash (/) character, but smaller, and written immediately above the vowel. For the lowercase 'i', the slash takes the place of the dot, so there is never an accent and the dot together. The HTML character entities for these accented characters are:
Á (Á) and á (á)
É (É) and é (é)
Í (Í) and í (í)
Ó (Ó) and ó (ó)
Ú (Ú) and ú (ú)

shallot tells me that the acute symbol is also used in most Slavic languages, Hungarian and other languages.
