Infinitives and infinitive phrases are important components of English grammar. They are verb forms that are used to express various functions and ideas. In this lesson, we will explore what infinitives and infinitive phrases are, how they are formed, and how they are used in sentences.

I. What are infinitives? Infinitives are the base form of a verb, usually preceded by the word β€œto.” They are not conjugated and do not indicate tense, number, or person. Infinitives can function as nouns, adjectives, or adverbs in a sentence.

Examples: - To eat (noun: subject of the sentence) - To run (adjective: modifies a noun) - To study (adverb: modifies a verb)

II. Forming infinitives: To form an infinitive, simply use the base form of a verb and add β€œto” before it.

Examples: - Base form: eat β†’ Infinitive: to eat - Base form: run β†’ Infinitive: to run - Base form: study β†’ Infinitive: to study

III. Infinitive phrases: An infinitive phrase consists of an infinitive and any accompanying words or phrases. These additional elements can include adverbs, adjectives, nouns, or prepositional phrases. Infinitive phrases can function as nouns, adjectives, or adverbs in a sentence.

Examples: - To eat a healthy breakfast (noun: subject of the sentence) - To run in the park (adjective: modifies a noun) - To study for the exam (adverb: modifies a verb)
