The infinitive form of a verb refers to the verb in its basic form. It is the version of the verb which will be found in the dictionary. The infinitive form of a verb is usually preceded by to. The word to is not a preposition. An infinitive is a non-finite verb. That is to say, it cannot be the main verb in a sentence.
