Past Infinitive
The past infinitive is used to express something that has already happened. Verbs such as s'excuser, regretter, and remercier are often used inthis tense. It is formed with the infinitive of the auxiliary verb(avoir or être) and the past participle of the main verb. And the pastparticiple can have agreement as well, with either the subject or theobject, depending on the sentence. Whenever après is followed by a verb, it is always a past infinitive. And note that negative expressionsprecede an infinitive.
