[edit] Usage

For the verbs aller, arriver, descendre, entrer, monter, mourir, naître, passer, partir, rentrer, rester, retourner, sortir, tomber, and venir, the auxiliary verb is être.
For pronomial verbs (verbs indicating that the subject performs the action upon itself) être is the auxiliary verb.
For all other verbs, avoir is the auxiliary verb.
When a verb that is normally conjugated with être is used transitively (along with a direct object), avoir is the auxiliary verb.
When a pronomial verb is used with an indirect object, avoir is the auxiliary verb.
