CONVERSION OF DIRECT INTERROGATIVE SENTENCES INTO INDIRECT SPEECH
Rules of change:
(i) If the direct speech is in interrogative sentence, Reporting Verbs such as say, tell etc. are changed into ask, esquire, want to know etc. in the indirect speech and the verb takes an object.
(ii) If the reported speech beginning with helping verb(is, am, are, was, were, do, does, did, has, have, had, will, would, can, could, shall, should, may, might, must) remove the inverted commas and use ‘if’ or ‘whether’ “that” is not used to join the reporting verb and reported speech.
(iii) If the direct speech begins with some ‘Wh’ question word, such as who, what, where, why, how, etc. these are retained in the indirect speech.
(iv) Helping verb should be put after the subject of the reported speech.
(v) But if the direct speech does n`t begin with such question words, if or whether is used as the linker.
(vi) The order of the words in the indirect speech is changed from the interrogative construction to the assertive construction and the note of interrogative (?) becomes full stop (.)
(vii) An interrogative sentence beginning with shall takes the form would in the past tense in the indirect speech. But should is retained when it implies a matter of duty.
