Let us understand the concept of reported speech clearer here:
We may report the words of a speaker in two ways- We can either quote his actual words which would then be called direct speech.
Ethan said, “I am very busy right now.”
Farhan asked, “Why didn't you come?”
We may also report what he said without quoting his exact words.
Ethan said that he was very busy then;
Farhan asked why I didn't go.
While changing the voice, few rules need to be taken into consideration such as:
A simple present becomes a simple past;
A present continuous becomes a past continuous;
A present perfect becomes a past perfect
She said, “I don't want to go.” becomes She said that she didn't want to go.
She said, “I am not going.” becomes She said that she wasn't going.
She said, “I didn't go.” becomes She said that she hadn't gone.
