Conditional 1 (zero, first, second)

INTRODUCTION TO CONDITIONAL

Some sentences with the word ‘if’ are called conditional sentences.

With every conditional sentence, there are two parts: a situation and the result of that

situation. It is the situation that starts with ‘if’.

There are different types of conditional sentence, depending on what the situation is.

Helpful hints



When we start the sentence with ‘if’, we separate the situation and the result with a

comma.
