Answer:
Infinitives are a special form of verbs that can be used as a noun, adjective, or adverb. They are usually made by adding the word to before the base verb, and they can be useful when discussing actions without actually doing the action, such as “I want to go home,” or “To err is human.”
Explanation:
The purpose of infinitives is to discuss an action in general instead of a specific instance of the action being done. For example, take a look at these two sentences:
I need to win.
Today, we win.
The first sentence uses the infinitive form of the verb win as a noun; the main verb of the sentence is actually “need.” The second sentence uses the standard form of win as an actionable verb. In the first sentence with the infinitive, the action of “winning” is not actually done; the sentence simply discusses the idea of winning. The second sentence, however, describes the action of winning.
