Conditional clauses

Conditional clauses

1. Are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled,

2. We can also use conditional conjunctions (since, unless, as long as, in case, provided that) to indicate that a condition must be fulfilled for another thing to happen.

3. -If I find her address, I’ll send her an invitation.
