When do we use the infinitive tense?

The infinitive tense is used in various situations. Here are some common instances when we use the infinitive tense:

1. To express purpose or intention: We use the infinitive tense to indicate the reason or purpose behind an action. For example, "I went to the store to buy some groceries."

2. After certain verbs: Certain verbs are followed by the infinitive tense. These verbs include "want," "need," "like," "love," "hate," "prefer," "plan," "decide," and many others. For example, "She wants to become a doctor."

3. After adjectives: Some adjectives are followed by the infinitive tense to describe a quality or characteristic. For example, "He is happy to help."

4. After certain nouns: Certain nouns are followed by the infinitive tense to express the purpose or function of the noun. For example, "I have a book to read."

5. In reported speech: When reporting someone's words or thoughts, we often use the infinitive tense. For example, "She told me to study harder."

6. In exclamatory sentences: The infinitive tense can be used in exclamatory sentences to express surprise, admiration, or other emotions. For example, "To win the lottery would be a dream come true!"

It is important to note that the infinitive tense is not affected by time or subject agreement. It is typically formed by using the base form of the verb, preceded by "to."
