Infinitive

The document discusses infinitives in sentences. An infinitive is a verb form that can function as the subject, predicate, or object of a sentence. The structure of a sentence is explained as subject + verb/modal/be + complement/object/adverb. Examples are given of sentences using infinitives to express purpose or intent after verbs like "want", "go", and "come". Infinitives are also used after modals, verbs of perception, and certain other verbs like "let" and "make".
