Updated Conditional Sentences rules For Competitive Exams


What is conditional sentence?

A conditional sentence consists of two parts first is a condition and another is a main clause. If A goes, B comes. If the sun sets, the moon arises.


If it rains, he will have a bath.

In the above example ‘If it rains is a condition and ‘he will have a bath is the main clause because the precedent action which is about a bath totally depends on the first action which is a condition. Hence it is a conditional sentence.

The Main Clause: It is a part of a sentence and doesn’t depend on anything. It can give its meaning alone. It is also called an independent clause.

Types of conditional sentences

   A general rule for conditional sentences

The condition in the sentence should never be in the future tense.

Example: If Rakesh will learn affiliate marketing, he will make a lot of money. ×

Here the condition is affiliate marketing hence it should not be in the future tense.

If Rakesh learns affiliate marketing, he will make a lot of money.

Here the rule is applied as per the requirement hence it is an accurate sentence.

Type 1 Present

Formation: In the first type of conditional sentence we hope that the first action will come into existence only then another will happen. Therefore we always use the condition in the present tense and the second part of the sentence in the future indefinite tense.
