Infinitive

An infinitive is a verb form whose subject slot is blocked so that it does not function as the main verb of an independent clause. However, it does designate a situation core, so it may function as the head of a (non-finite) dependent clause. Morphologically, it is a non-finite form which is crucially not specified for person, number and mood. Other categories which may or may not be absent include tense, aspect and voice.

The infinitive is a kind of non-finite verb.

The infinitive is a kind of verbal noun.
