Thanks. Oh, so um, for "I have eaten" or "I have ate", in french it would have a "me" in it?Welcome to the Forum! We need more context in order to help you. In what context do you want to know which expression to use?
In very general terms:"Je suis" = "I am." "Je me suis" is most commonly followed by the past participle of a verb and means "I _____ed myself."
