An acute accent is a symbol that is placed over vowels in some languages in order to indicate how that vowel is pronounced or over one letter in a word to indicate where it is stressed. You refer to a letter with this accent as, for example, e acute. For example, there is an acute accent over the letter 'e' in the French word 'café'.
