There are three main tenses (forms of verbs):
1. Present Tense – the time that is passing.
2. Past Tense – the time that has passed.
3. Future Tense – the time to come.
Thus, Present tense expresses actions in the present time, past tense expresses actions in the past time, and future tense expresses actions in the future time. For example:
(i) Sumit scores good marks. (Present tense)
(ii) Sumit scored good marks. (Past tense)
(iii) Sumit will score good marks. (Future tense) The tense of a verb shows the time of an action or an event. It also shows continuance and perfection of it.
Each of these three main tenses has four kinds:
I. Simple or Indefinite
II. Continuous or Progressive
IV. Perfect Continuous
