Bonjour Nicholas ! In the case of indirect objects - complements to the verb introduced by a preposition "à" or "de" - following the pattern "à + stress pronoun", in French they need to be replaced altogether by indirect object pronouns: "me, te, lui, nous, vous, leur". Here are links to our related lessons: Me/te/nous/vous = Me/you/us/you (French Direct and Indirect Object Pronouns) Using lui/leur = him or her/them (French Indirect Object Pronouns) I hope that's helpful! À bientôt !
