What Is An Infinitive?
What is an infinitive? An infinitive is a verbal consisting of to + a verb, and it acts like a subject, direct object, subject complement, adjective, or adverb in a sentence. Infinitives are easy to identify because they’re written with to + a verb.
Infinitive examples:
To give
To run
To wait
Although an infinitive is easy to locate because of the to + verb form, deciding what function it has in a sentence can sometimes be confusing.
