The rules
- A that clause can be the object of a verb such as think, know or say: I think that the test will be easy.
- A clause can be the subject of a sentence, and then it takes a singular verb: What she said was true.
- Use whether or if for a yes/no question inside a sentence, but only whether at the start or after a preposition: I wonder whether it will rain.
- An indirect question uses statement order, with no do, does or did: I wonder where he lives.
- Use what when the clause is missing a thing, and that when the clause is already complete: What he needs is time, and I know that he needs time.
- After a past reporting verb, the tense usually moves back: She said, “I am tired” becomes She said that she was tired.
