An infinitive is to plus a verb form. It can be used as an adverb. Examples: to be, to see, to be seen, to be eaten.
Adverb infinitives are used to modify verbs. They usually tell why.
An infinitive phrase is made up of an infinitive and any complements (direct objects, predicate nominatives, predicate adjectives, or modifiers.) An infinitive phrase that comes at the beginning of the sentence is always followed by a comma and modifies the subject of the sentence.
