2. (law) to convict [with de]

Conjugation

This verb is conjugated like vaincre. That means it is conjugated like vendre, except that its usual stem convainqu- becomes convainc- when either there is no ending, or the ending starts with -u- or a written consonant. Additionally, when inverted the third person singular in the present adds the infix -t-: convainc-t-il? These are strictly spelling changes; pronunciation-wise, the verb is conjugated exactly like vendre.
