Tenses in English Grammar - 12 Tenses Rules, Examples and Sequence

What are Tenses in English Grammar?

Tense shows the time of an action or event. It tells whether an action happens in the present, past, or future. In English, there are three main times and four aspects for each time, making a total of 12 tenses. Understanding tenses is essential for correct sentence formation, especially in competitive exams like SSC, Railway, Banking, and CTET where tense errors are frequently tested.

Important Fact: Every tense has four aspects: Indefinite (Simple), Continuous, Perfect, and Perfect Continuous. The verb form changes according to tense and aspect. For example, go becomes goes in present indefinite, is going in present continuous, has gone in present perfect, and has been going in present perfect continuous.

Present Indefinite is used for habits, universal truths, and daily routines. Structure is Subject + V1 + s/es + Object. Present Continuous shows action happening now. Structure is Subject + is/am/are + V1+ing. Present Perfect shows completed action with present relevance. Structure is Subject + has/have + V3. Present Perfect Continuous shows action started in past and continuing now. Structure is Subject + has/have been + V1+ing + since/for.

2. Past Tenses

Past Indefinite shows completed past action. Structure is Subject + V2 + Object. Past Continuous shows ongoing action in past. Structure is Subject + was/were + V1+ing. Past Perfect shows earlier past action before another past action. Structure is Subject + had + V3. Past Perfect Continuous shows continuous action up to a point in past.

Past Indefinite	Sub + V2	She wrote a letter yesterday.
Past Perfect	Sub + had + V3	She had written before he came.
Future Indefinite	Sub + will + V1	She will write a letter tomorrow.

Tense Identification and Sequence of Tenses

Tense identification requires looking at verb form, helping verb, and time marker like yesterday, since, for, tomorrow. Sequence of tenses means if main clause is in past, subordinate clause should be in past. For example, He said that he was ill is correct, not He said that he is ill. If main clause is present or future, subordinate clause can be any tense according to meaning. This rule is highly tested in narration and complex sentences in SSC and Banking exams.

Exam Tip: For SSC CGL and CHSL, focus on Present Perfect vs Past Indefinite difference, use of since and for with perfect continuous, and sequence of tenses in reported speech. Many errors come from using present perfect with past time markers like yesterday, which is incorrect.
