Overview
When reporting speech at a later time, tenses usually backshift: present simple → past simple, present continuous → past continuous, past simple → past perfect, will → would, can → could, may → might. Backshift is optional when the reported information is still true or was said very recently.
The Backshift Rule
- When the reporting verb is in the past, tenses normally shift back one step.
- present → past
- past → past perfect
- will → would
- can → could
When NOT to Backshift
- No backshift needed when the statement is still true.
- FactShe said the Earth orbits the Sun. ✓
- RecentHe said the train leaves at 9. (still valid) ✓
- GeneralShe said she loves music. (still true) ✓
