What do Infinitive and Past Tense Mean?

Infinitive and past tense are two important concepts in English grammar. They are used to describe actions that have already happened or actions that are yet to happen. In this article, we will learn more about these concepts and how they are used in English.

Infinitive

Infinitive is the base form of a verb. It is used to describe an action that has not yet happened. For example:

1. I want to go to the park.
2. She likes to play the guitar.
3. He needs to study for the exam.

In all these sentences, the verbs "go," "play," and "study" are in their infinitive form. They are used to describe actions that have not yet happened. Infinitive verbs are often used with the word "to."

Past Tense

Past tense is used to describe actions that have already happened. For example:

1. I went to the park yesterday.
2. She played the guitar last night.
3. He studied for the exam all day.

In all these sentences, the verbs "went," "played," and "studied" are in their past tense form. They are used to describe actions that have already happened in the past.

Infinitive and Past Tense in a Sentence

Infinitive and past tense can be used together in a sentence to describe actions that happened in the past. For example:

1. I wanted to go to the park, but it rained.
2. She liked to play the guitar, but she broke her arm.
3. He needed to study for the exam, so he stayed up all night.

In all these sentences, the verbs "wanted," "liked," and "needed" are in their past tense form, while the verbs "go," "play," and "study" are in their infinitive form. This combination of infinitive and past tense is often used to describe actions that did not happen because of some reason.

Infinitive is used to describe actions that have not yet happened, while past tense is used to describe actions that have already happened. These two concepts are often used together in a sentence to describe actions that did not happen because of some reason.
