The passé composé is a French compound tense used to express completed actions in the past. It is formed by combining the present tense of an auxiliary verb (avoir or être) with the past participle of the main verb. It generally translates to the English simple past ("I ate") or present perfect ("I have eaten").
In the passé composé, the auxiliary verb has to be conjugated in the present tense and always agree with the subject, i.e. change according to the person it refers to, as in the following examples: J'ai mangé (I have eaten) Tu as mangé (you have eaten) Il a mangé (he has eaten), etcThe passé composé (pronounced [pase kɔ̃poze]; 'compound past') is a past tense in the French language. It is used to express an action that has been finished completely or incompletely at the time of speech, or at some (possibly unknown) time in the past. It originally corresponded in function to the English present perfect, but now there is a tendency to use it for all completed actions in the past as the equivalent of the simple past. Its current usage corresponds fairly closely to that of the Latin perfect tense. It is formed using an auxiliary verb and the past participle of a verb.
