Question

He said to mi " where you bring me a glass off water"(chenge into indirect speech)​

Answer 1

Question : He said to me, "will you bring me a glass of water?"

Answer :

1. He asked me if I would bring him a glass of water. (Interrogative Sentence)
2. He wished for a glass of water. (Optative Sentence)

[ But it is advisable to use the Interrogative Sentence Indirect Speech. Here the Optative one looks sensible though. ]
