Extra Information ↴

In the Direct & Indirect Speech, we usually change the tense of the Direct Speech when we change it to the Reported speech, but in the case of Simple Future tense we do not change the tense of the direct speech after converting it to the reported speech.

The Helping verb of Simple Future tense will convert to 'would' in the Indirect (reported) Speech.
