If Clauses – Type 1


Conditional clauses consist of two sentences. One is a clause that starts with if, which is called as ‘if clause’. The other is called the Main clause. Each sentence has a verb. It is important to know which tenses are to be used in these clauses and they play a big role in determining the meaning of the sentence.
