The perfect tense with AVOIR

Updated: Sep 7, 2020

Unlike the present tense, which is made up of one word (e.g: je donne), the perfect tense has two parts to it:

  1. an auxiliary: AVOIR or ÊTRE in the present tense

  2. the past participle of the main verb

The perfect tense in French is like the form: I have watched in English.
