Conditional Clause
The conditional sentences tell us that if a certain condition is true, then a particular result
happens. In a conditional sentence, one of the clauses lays down the condition called the
conditional clause, while the second one gives the result.
Read the sentences given below.
• I would have joined the army if I had had the opportunity.
• If I knew her address, I would have met her.
Here, all the highlighted groups of words are conditional clauses.
When the ‘if’ clause precedes the main clause, a comma is used after it.

There are four types of conditional clauses:
1. Conditional Type 0 2. Conditional Type 1
