INFINITIVE CONSTRUCTIONS - PART 1
As we already know, the infinitive is the basic form of a verb. It expresses the idea of a verb’s meaning without being conjugated. In English, the infinitive is the word "to" followed by a verb: to talk, to see. The French infinitive is a single word with one of the following endings: -er, -ir, or -re.
The French infinitive can be used in several different ways without any conjugation. It can be used as a noun, after a preposition, after a conjugated verb, as well as an imperative.
