How do you say won't in french?

Answer 1

"won't" has no single translation in French. To indicate that an action will not take place, the French use the verb in its future tense, with the negative (ne .... pas, n'.... pas).

je n'irai pas (verb "aller" at the future tense + negative marker) = I won't go

elle ne le dira pas (verb "dire" at the future tense + negative marker) = she won't say

nous ne mangerons pas au restaurant = we won't eat at the restaurant
