    • Example: She went to the store to buy groceries. (The purpose is buying groceries.)

  2. After Certain Verbs:

    • Example: He wants to travel around the world. (The verb "wants" is followed by the infinitive "to travel.")

  3. As a Subject:

    • Infinitives can be the subject of a sentence, emphasizing an action or idea.

    • Example: To read is a great way to relax. (The infinitive "to read" is the subject of the sentence.)

  1. To Express Purpose:

    • Use infinitives when you want to explain the reason or goal behind an action.

    • Example: She practices every day to become a better musician. (The purpose of practicing is becoming a better musician.)

  2. After Certain Verbs:

    • Infinitives often follow verbs like "want," "need," "like," and "decide."
