An infinitive verb in English is the base form of a verb, typically preceded by the word “to.” It represents the purest and most basic form of a verb and is not conjugated to show tense, person, or number.
For example, “to run,” “to eat,” and “to write” are infinitive verbs. Infinitives can function as nouns, adjectives, or adverbs in a sentence.
They are versatile and used in a wide range of contexts, making them an essential element of English grammar for expressing actions, purposes, or intentions.
