Tenses (Time of Action)

A part of speech is a category of words that have similar grammatical properties and functions within a sentence. Understanding parts of speech is fundamental to comprehending how language works and how to construct grammatically correct and meaningful sentences.

There are traditionally eight parts of speech in English:

1.    Noun

2.    Pronoun

3.    Verb

4.    Adjective

5.    Adverb

6.    Preposition

7.    Conjunction

8.    Interjection

Tenses (Time of Action)

In grammar, tenses refer to the way verbs are used to indicate the time when an action or state of being occurs. They allow us to express whether something happened in the past, is happening now, or will happen in the future. Tenses also convey information about the duration and completion of an action.

There are three main time divisions in tenses:

1.     Past Tense

2.     Present Tense

3.     Future Tense

Each of these main tenses further branches into four aspects:

• Simple
• Continuous (or Progressive)
• Perfect
• Perfect Continuous (or Perfect Progressive)

This gives us a total of 12 common tenses in English. Let's explore each with full descriptions and examples.
