How do you say ate in french?

Answer 1

In French, the preposition à is generally used in cases where we would use to, in, or at. It should be noted however that in some idiomatic expressions the French do not always use the literal translation of whatever word we would use in the same context.

Answer 2

'ate' is the participle "mangé" in French.

I ate: j'ai mangé

we ate the cake: nous avons mangé le gâteau.

Answer 3
