The auxiliary verb also is called a helping verb. For it's used to help form the tenses that are composed of two verbs. An example is the past tense that's called 'passe compose', or 'composed past'. It's composed of the auxiliary verb 'avoir' ['to have'], or 'etre' ['to be']. In this particular tense, the auxiliary verb is in the present tense. The main verb is in the form of the past participle, which isn't conjugated. But those that take 'etre' agree with the subject in feminine/masculine gender and in singular/plural number. For example, the verb 'parler' ['to speak'] takes 'avoir' in the composed tenses. In the passe compose tense, 'I did speak, have spoken, spoke' is 'J'ai parle'.
