Here's a breakdown:
1. Original Direct Speech:
```
S
|
-------
| |
NP VP
| |
John said
|
"I am happy"
```
2. Transformation:
* Change the tense: If the direct speech is in the present tense, we usually shift it to the past tense in indirect speech.
* Change pronouns: Pronouns need to be adjusted to reflect the perspective of the reported speech.
* Add reporting verb: A reporting verb like "said," "told," or "asked" is used to introduce the indirect speech.
3. Indirect Speech:
```
S
|
-------
| |
NP VP
| |
John said
|
that he was happy
```
Explanation:
* "John" remains the subject of the sentence.
* "Said" is the reporting verb.
* "That" acts as a conjunction introducing the indirect speech.
* "He" replaces "I" to match the perspective of the report.
* "Was happy" reflects the past tense shift from "am happy."
Important Notes:
* This is a simplified example. The actual transformation will depend on the specific tense, pronouns, and context of the direct speech.
* There are other ways to represent sentence structures, such as dependency trees, which might be more suitable for complex indirect speech examples.
