An infinitive phrase consists of the infinitive form of a verb, usually preceded by the word "to," along with any modifiers or complements. For example, in the phrase "to eat quickly," "to eat" is the infinitive, and "quickly" modifies it. Infinitive phrases can function as nouns, adjectives, or adverbs in a sentence. These phrases can express various ideas, such as purpose or intention. For instance, "to learn new skills" can indicate a goal. Infinitive phrases are versatile and can enhance writing by providing additional information about actions or intentions related to subjects like students or professionals.
