Understanding Direct and Indirect Speech
When converting direct speech to indirect speech, we need to make certain adjustments to the sentence structure, verb forms, and pronouns. In the example provided, Sapna's direct speech is: "I read my book every day."

Steps to Convert Direct Speech to Indirect Speech
1. **Identify the Speaker and the Statement:**
- The speaker is Sapna.
- The statement is about her reading habits.
2. **Change the Reporting Verb:**
- In indirect speech, we often use verbs like "said," "stated," or "mentioned." Here, we can use "said."
3. **Adjust Pronouns:**
- The pronoun "I" in direct speech changes to "she" in indirect speech, as we refer to Sapna.
4. **Modify the Verb Tense:**
- The present tense "read" can remain the same since it indicates a habitual action. However, if it were a specific instance, we would change it to past tense.
5. **Change Time Expressions:**
- The phrase "every day" remains unchanged, as it refers to a habitual action.

Final Conversion to Indirect Speech
Taking these adjustments into account, the sentence in indirect speech would be:
- **Sapna said that she reads her book every day.**

Key Points to Remember
- Use a reporting verb suitable for the context.
- Adjust pronouns to match the speaker and listener.
- Maintain the verb tense for habitual actions.
- Review time expressions for any necessary changes.
This structured approach will help ensure clarity when converting direct speech to indirect speech in various contexts, including UPSC exams.
