- 1st Person (I, we): Changes according to the Subject of the reporting verb.
- 2nd Person (you): Changes according to the Object of the reporting verb.
- 3rd Person (he, she, it, they): Remains unchanged (No Change).
Tense Backshift Table (When Reporting Verb is in the Past):
| Direct Speech Tense | Indirect Speech Tense |
|---|---|
| Simple Present (V1) | Simple Past (V2) |
| Present Continuous (is/am/are) | Past Continuous (was/were) |
| Present Perfect (has/have) | Past Perfect (had + V3) |

Exception: If the direct speech states a universal truth, habitual fact, or proverb, the tense never changes (e.g. The teacher said, 'The Earth revolves around the Sun.' → The teacher said that the Earth revolves around the Sun.).
