Definition & Meaning of "infinitive"

What is an "infinitive"?

An infinitive is the base form of a verb, usually preceded by the word "to." It is not limited by tense or subject, allowing it to function in various ways within a sentence. Infinitives can act as nouns, adjectives, or adverbs. For example, in the sentence "I want to read," the phrase "to read" is an infinitive acting as the object of the verb "want." Infinitives are important for expressing intentions, desires, or actions, and they help convey meaning in a flexible manner within sentences.
