Tense : Introduction
If we talk of the word ‘Tense‘, it is derived from the Latin word ‘Tempus’ which means time. Time is a dimension which expresses the state of the speech or sentence that we form. State shows if the action of the sentence is already done or is happening now or to happen later in future. The verb of a sentence shoulders the responsibility to express the time of the action or state. Thus, if we want to express an event that is already from the time passed by, we call it a past event and use the past form of the verb in; if the expression shows an event of now, we call it a present event and use the present form of the verb in; the same way, if the expression shows an event from any upcoming time, we name it a future event and use the method to make the verb represent a future time. So, tense can be broadly categorised into three kinds, i.e., I. Present Tense, II. Past tense and III. Future Tense.
Each of the aforementioned tenses can further be categorised into four sub-categories according to express its sense and exact timing. The sub-categories are, I. Simple or Indefinite, II. Continuous, III. Perfect and, IV. Perfect Continuous.
Let’s take a bird’s-eye view of all the categories of the tense below along with an example from each section.
1. Present Tense
- Sub + V1 + Obj
- Sub + do/does + not + V1 + Obj
- Wh- + do/does + Sub + V1 + Obj
- Wh- + don’t/doesn’t + Sub + V1 + Obj
Remember! for negative interrogative sentences we place ‘not‘ after the pronoun but, if there is a noun, we place ‘not’ before the noun. e.g.,
- Does he not go to college?
- Does not Raji go to college?
When to use Present Indefinite Tense?
We use present indefinite tense in various aspects. It is used for expressing universal truths. It is used to express regular habits. It is used in newspaper headlines. Remember, there cannot be two future tenses in a single sentence. One should be in the present indefinite and another in the future tense. The part having a conditional term should be in the Present Indefinite Tense. Sometimes present indefinite tense is used in the place of future indefinite when the action is certain and is of near future. It is used after the expression ‘had better’, ‘would better’, ‘had rather‘, ‘as usual‘, ‘usually‘, ‘generally‘, ‘sometimes‘, ‘never‘, ‘often‘, etc. Let’s go through examples from each aforementioned aspect.

It is used when there are some words in a sentence like, ‘just’, ‘just now’, ‘already’, ‘recently’, ‘so far’, ‘yet’, ‘as yet‘, ‘lately‘, ‘recently‘, ‘by now‘, ‘by the time of now‘, ‘by this time‘, ‘of late‘, etc. Let’s take a look at a few examples.

- Sub + have/has + not + been + V + ing + Obj + since/for + time

When to use Past Perfect Tense?
This is used to show two past events or actions in a single sentence. One event happed earlier than the other. Here, we use ‘before’ or ‘after’ to express the order of the events or actions. If we use ‘before‘ as the conjunction, the earlier event is placed first and ‘had‘ goes with the earlier event or action and the latter event is written in simple past or past indefinite. On the other hand, if we use ‘after‘ in place of ‘before’ the clauses interchange the places. Let’s go through a couple of examples to understand it better.
- I had reached the station before the train left.
- The train left after I had reached the station.
Remember! In a single sentence, there can’t be two simple past tenses. The action taking place earlier should take past perfect and the action taking place later on, should take simple past. If the part of past perfect comes first then ‘before’ is used but if it goes last then ‘after’ is used.
In case of three incidents in a single sentence:
The train left after I had reached the station and I got it easily.
- Then he was 18 his father had died before that time.
- I had completed my project by last week.
