What is Sequence of Tenses?

Definition

The Sequence of Tenses refers to the rule according to which the tense of a verb in the subordinate clause follows the tense of the verb in the principal (main) clause, so that the sentence remains grammatically correct and logically consistent.

In simple words, it explains:

Which tense should be used in the dependent clause when the tense of the main clause is fixed.

Example:

He says that he is ill. ✅
He said that he was ill. ✅

Why Sequence of Tenses is Important for Exams

It is directly tested in narration questions.
It helps in identifying grammatical errors.
It improves accuracy in sentence improvement questions.
It is essential for writing clear and correct English.

Basic Structure Involved in Sequence of Tenses

A sentence following sequence of tenses usually has two parts:

Principal Clause (Main Clause)
Subordinate Clause (Dependent Clause)

Example:

She said (principal clause) that she was tired (subordinate clause).

FUNDAMENTAL RULES OF SEQUENCE OF TENSES

There are three fundamental rules of sequence of tenses that govern almost all exam questions.

RULE 1: When the Principal Clause is in the Present or Future Tense

Rule Explanation

If the verb in the principal clause is in the present tense or future tense, the verb in the subordinate clause can be in any tense, depending on the sense of the sentence.

Key Point

No restriction is applied to the subordinate clause when the main clause is in present or future tense.

Examples (Present Tense in Main Clause)

He says that he works hard. (present)
She says that she worked hard. (past)
I think that he will succeed. (future)
We believe that she has completed the task. (present perfect)

Examples (Future Tense in Main Clause)

He will say that he is innocent.
She will believe that the plan will work.

Exam Note

This rule is often tested indirectly through error detection questions.

Incorrect: He says that he was a good player now. ❌
Correct: He says that he is a good player now. ✅

RULE 2: When the Principal Clause is in the Past Tense

This is the most important rule of sequence of tenses and is frequently tested in exams.

Rule Explanation

If the verb in the principal clause is in the past tense, the verb in the subordinate clause must also be in a corresponding past tense.

In simple words:

Past tense in main clause → Past tense in subordinate clause

Present → Past

Direct Form	Indirect Form
Present Indefinite	Past Indefinite
Present Continuous	Past Continuous
Present Perfect	Past Perfect

Examples:

He said that he worked hard.
She said that she was reading a book.
They said that they had completed the work.

Past → Past Perfect / Past Indefinite (as required)

Examples:

He said that he had lost his keys.
She said that she went there yesterday.

Future → Conditional (Would / Should)

Examples:

He said that he would help me.
She promised that she would come.

Exam Tip

In narration questions, verbs like said, told, asked, promised immediately signal the application of Rule 2.

RULE 3: Universal Truth, Habitual Facts, and Scientific Statements

Rule Explanation

When the subordinate clause expresses a universal truth, habitual fact, or scientific principle, the verb remains in the present tense, even if the principal clause is in the past tense.

Examples

The teacher said that the sun rises in the east. ✅
He said that honesty is the best policy. ✅
Galileo said that the earth revolves around the sun. ✅

Incorrect: The teacher said that the sun rose in the east. ❌

Sequence of Tenses in Conditional Sentences

Zero Conditional

Used for universal truths; present tense is used in both clauses.

If you heat ice, it melts.

First Conditional

If he comes, I will help him.

Second Conditional

If I were rich, I would help the poor.

Third Conditional

If he had worked hard, he would have succeeded.

Sequence of Tenses in Time Clauses

Important Rule

In time clauses beginning with:

when
while
before
after
until
as soon as

Future tense is not used, even if the meaning refers to future time.

Examples:

I will wait until he comes. ✅
She will call you when she reaches home. ✅

Incorrect: I will wait until he will come. ❌

Sequence of Tenses in Relative Clauses

Examples:

He met a man who was living in poverty.
She bought a book that explains grammar clearly.

The tense depends on the meaning and context, not blindly on the main clause.

Sequence of Tenses in Narration (Direct–Indirect Speech)

This is one of the most tested areas related to sequence of tenses.

General Rule

When the reporting verb is in the past tense, the tense of the reported speech changes according to sequence rules.

Tense Changes in Narration

Direct Speech	Indirect Speech
Present Indefinite	Past Indefinite
Present Continuous	Past Continuous
Present Perfect	Past Perfect
Past Indefinite	Past Perfect
Will	Would

Example

Direct: He said, “I am tired.”
Indirect: He said that he was tired.

Common Errors in Sequence of Tenses

Ignoring universal truth rule
Using future tense in time clauses
Wrong tense shift in narration
Mechanical application without context

Error Detection Examples

He said that he is very poor. ❌
He said that he was very poor. ✅
