How do you say didn't in french?

Answer 1

Well, you don't, really. "didn't" is used in English to form the negative past tense. This is because we add forms of the verb "to do" in front of verbs when they become negated. This is a unique feature of English.

For example:

I like cheese. / I don't like cheese.

I ate mold. / I didn't eat mold.

So what you're really asking is how to negate a past tense in French. This is done the same as any other tense--by putting "ne" before the verb and "pas" after the verb.

For example:

Vous saviez. (You knew.) / Vous ne saviez pas. (You didn't know.)

J'ai fait la vaisselle. (I did the dishes) / Je n'ai pas fait la vaisselle. (I didn't do the dishes.)

Answer 2

"Didn't" in French is "n'a pas" or "n'a pas fait" when referring to actions.
