    If clause and main clause

    We use if + past perfect to talk about an imaginary or hypothetical situation in the past. And we use would have, could have or might have + past participle in the main clause to talk about the result or consequence of that imaginary situation.

    • If you had come to class more often, you would have passed the test.
    • If he hadn’t taken his helmet, he could have died.
    • If the jacket had been a bit cheaper, I might have bought it.


    As with all conditional types, we use a comma after the ifclause when it goes at the beginning of the sentence, but we don’t use a comma when the if-clause goes at the end.

    • If I hadn’t overslept, I wouldn’t have been late.
