Question

what is indirect and direct speech?

Answer 1

Indirect Speech
Reported or indirect speech is usually used to talk about the past, so we normally change the tense of the words spoken. We use reporting verbs like 'say', 'tell', 'ask', and we may use the word 'that' to introduce thereported words. Inverted commas are not used.
Direct Speech
Direct speech is a report of the exact words used by a speaker or writer. Contrast with indirect speech. Also called direct discourse. Direct speechis usually placed inside quotation marks and accompanied by a reporting verb, signal phrase, or quotative frame
