An infinitive is the most basic form of a verb, typically preceded by the word “to.” In English, it comes in two forms: the “to-infinitive” (e.g., to run, to write) and the “bare infinitive” (e.g., run, write). They serve various\u00a0functions in sentences, acting as nouns, adjectives, or adverbs.<\/p>\n

Ex: To eat (To-infinitive)
Ex: Eat (Bare infinitive)<\/p>\n\n\n

Functions of Infinitives<\/h2>\n\n\n

As a Noun<\/strong>
Infinitives can serve as subjects, direct objects, or subject complements.<\/p>\n

Ex: To sleep<\/strong> is the only thing I desire right now. (Subject)
Ex: I like to read<\/strong> novels. (Direct Object)
Ex: My goal is to graduate<\/strong>. (Subject Complement)<\/p>\n

As an Adjective<\/strong>
Infinitives can modify nouns, often answering the question of \u201cwhich one?\u201d<\/p>\n

Ex: I need a book to read<\/strong>. (Which book? The book to read.)<\/p>\n

As an Adverb<\/strong>
Infinitives can modify verbs, adjectives, or other adverbs.<\/p>\n

Ex: I came here to learn<\/strong>. (Modifying the verb “came”)
Ex: She is eager to help<\/strong>. (Modifying the adjective “eager”)<\/p>\n\n\n

Split Infinitives<\/h2>\n\n\n

A split infinitive is an infinitive that has an adverb between “to” and the verb.<\/p>\n

Ex: To boldly<\/strong> go where no one has gone before.
Ex: She decided to quickly<\/strong> eat before the meeting.<\/p>\n

Split infinitives are often considered more casual, but they are generally accepted in modern English.
However, for formal writing, it\u2019s often advised to avoid them.<\/p>\n\n\n

Infinitive Phrases<\/h2>\n\n\n

An infinitive phrase includes the infinitive and any accompanying objects, modifiers, or both.<\/p>\n

Ex: To write a bestselling novel (To write + a bestselling novel)
Ex: To swim across the lake (To swim + across the lake)<\/p>\n\n\n
