What is it?

An infinitive phrase is a group of words that starts with an infinitive (the base form of a verb, usually preceded by 'to'). This phrase acts like a noun, adjective, or adverb in a sentence, giving more information about what is happening or why. It tells us the purpose or goal of an action.

Why It Matters

Understanding infinitive phrases is crucial for clear communication and writing. Journalists use them to precisely convey information, and lawyers depend on them to write clear contracts. In communication, they help you express your intentions and purposes accurately, whether you're explaining a science project or writing a story.

Common Mistakes

MISTAKE: Confusing an infinitive phrase with a prepositional phrase. For example, in 'I went to the park,' 'to the park' is a prepositional phrase, not an infinitive phrase. | CORRECTION: An infinitive phrase always starts with 'to' followed by a verb (like 'to run', 'to eat'). A prepositional phrase starts with 'to' followed by a noun or pronoun (like 'to school', 'to him').

MISTAKE: Forgetting to include all the words that complete the infinitive's meaning. For example, in 'She loves to sing folk songs,' identifying only 'to sing' as the phrase. | CORRECTION: The infinitive phrase includes the infinitive and all the words that modify or complete its meaning. So, 'to sing folk songs' is the full phrase.

MISTAKE: Thinking that any 'to' in a sentence makes it an infinitive phrase. | CORRECTION: The word 'to' must be immediately followed by the base form of a verb for it to be an infinitive. If 'to' is followed by a noun or pronoun, it's usually part of a prepositional phrase.
