Rules for converting direct speech to indirect speech-
· When the reporting verb of direct speech is in past tense then all the present tenses are changed to the corresponding past tense in indirect speech. 
· Reporting verbs such as ‘said/ said to’ changes to said, told.
· Comma inverted comma will be replaced with conjunction “That”.
· The  first person in direct speech  changes as per the subject of the speech.
· The  second person of direct speech  changes as per the object of reporting speech.
· The  third person of direct speech  doesn’t change.
The correct indirect speech form of "The teacher said, 'The university will be closed tomorrow.'" involves changing 'will' to 'would' to reflect a shift from direct to reported speech.
This maintains the original meaning while correctly adapting the verb tense for reported speech.
