Introduction
In this chapter, we will learn about infinitive phrases. Infinitive phrases are groups of words that include an infinitive (to + base form of a verb) and any words that modify it. Understanding infinitive phrases helps us add detail and clarity to our sentences by indicating purpose, intention, or the result of an action.

An infinitive is the base form of a verb with the word “to” in front of it, such as “to run” or “to dance.” For example, “to eat healthily every day” is an infinitive phrase in the sentence “She aims to eat healthily every day.”
