Rules Regarding Sequence of Tenses with Examples
Learning and understanding the rules for using multiple verbs in a sentence is essential to comprehend the sequence of tenses. Associating examples with these rules is crucial for mastering them. Below are the rules to follow when using multiple tenses:
Rule 1: Past Follows Past
If the main clause has a verb conjugated in the past tense, ensure that the subordinate clause also uses the past tense. This rule can be nuanced based on the form of past tense in the principal clause.
Tense of the Principal Clause | Tense of the Subordinate Clause | Example |
Simple Past | Simple Past |
|
Past Continuous | Simple Past |
|
Past Perfect | Simple Past |
|
Simple Past | Past Perfect |
|
Simple Past | Past Perfect Continuous |
|
Exceptions to Rule 1:
Present Follows Past:
In cases where the subordinate clause conveys a general fact, routine action, or universal truth, use the present tense even if the principal clause has a past tense verb.
Example: The teacher taught us today that the Earth revolves around the Sun.
Any Tense in the Subordinate Clause:
When making a comparison using 'than,' there is no specific rule for choosing the tense.
Example: I would prefer going shopping with you rather than sitting at home all day doing nothing.
Rule 2: Any Tense after Present or Future Tense
If the principal clause is in the present or future tense, the subordinate clause can take any tense based on the conveyed information.
Tense of Principal Clause | Example |
Present | He says he sees Krishna. |
Future | My mom will be happy if you come home. |
She thinks that the food here is good. |
Rule 3: Present Follows Future
When using subordinating conjunctions like 'when,' 'as soon as,' 'after,' etc., the subordinate clause takes the present tense when the verb in the principal clause is in the future tense.
Example |
I will teach you after I finish learning. |
Aruna will help her mom once she completes her assignments. |
More Examples
I'll join the team after I finish my training. (NOT I'll join the team after I will finish my training.)
She promises to call before she leaves. (NOT She promises to call before she will leave.)
If you put in the effort, you'll excel. (NOT If you will put in the effort, you'll excel.)
The Present Perfect Tense in Subordinate Clauses
The present perfect tense is frequently used in subordinate clauses to denote future events. Remember, this construction is applicable only when the main clause verb is in the present or future tense.
We won't start the project until they have reviewed our proposal. (NOT We won't start the project until they will have reviewed our proposal.)
After I've had my meeting, we can discuss your ideas. (NOT After I will have had my meeting, we can discuss your ideas.)
Rule 4: Use of Past Tense in Subordinate Clauses
When using phrases like 'as if,' 'it is time/high time,' 'what if,' 'wish that,' etc., use the past tense form of the verb.
Example |
I wish I had known you earlier. |
She acted as if none of this affected her. |
It is high time you consulted a doctor. |
Rule 5: Use of Modal Verbs When the Conjunction 'That' Is Used
If a subordinate clause starts with the conjunction 'that' or 'so that,' use 'may' for present tense in the principal clause and 'might' for past tense.
Example |
We work hard so that we may prosper. |
They worked hard so that they might not perish. |
