Overview
Sequence of tenses refers to how verb tenses in subordinate clauses are adjusted to be consistent with the main clause tense. In reported speech, tenses backshift. In conditional sentences, specific tense combinations apply. In time clauses referring to the future, present simple is used (not future): When she arrives, I will tell her. Understanding tense sequence prevents logical inconsistency in complex sentences.
What Is Sequence of Tenses?
- definitionHow tenses in subordinate clauses align with the main clause.
- reportedMain: past → subordinate: backshifts. She said she was tired.
- conditionalIf + present → will. If + past → would.
- time clauseWhen she arrives (NOT: will arrive), I will tell her.
- keyEnsures logical time consistency across clauses.
Key Patterns
- reportedHe said he would be late.
- 1st cond.If you study, you will pass.
- 2nd cond.If she had time, she would help.
- time clauseAfter she finishes, we will eat.
- past ref.By the time he arrived, she had left.
Common Mistakes
- ❌ When she will arrive, I'll call → ✅ When she arrives.
- ❌ She said she is tired → ✅ She said she was tired.
- ❌ If he will come, we eat → ✅ If he comes, we will eat.
