What Is It?

Backshifting refers to the tense movement often used when reporting earlier speech.

B1-B2 reference topic in Reported Speech.

Why Use It?

Show that the original speech happened before the report.
Keep time relationships clear.
Use past forms after past reporting verbs.

Formation and Patterns

Use	Pattern	Example
Present to past	`am/is/are -> was/were`	She said she was busy.
Past to past perfect	`did -> had done`	He said he had finished.

Common Mistakes

Backshifting mechanically when the fact is still true and context favors the present.
