What Is the First Conditional?

The first Conditional is used to speak about actual and possible situations in the destiny and their predicted consequences. These situations are not imaginary. There may be a real hazard that could take place.

Easy clarification:

  • The primary Conditional indicates a possible destiny situation and its result.

Example:

  • If it rains, I will take an umbrella.

Rain is possible and taking an umbrella is a logical end result.

Definition of First Conditional

First Conditional is a type of conditional sentence used to describe real future possibilities and what will happen if those possibilities become true.

It connects:

  • A condition (something that may happen)
  • A result (what will happen because of it)

Basic Structure of First Conditional

The most not unusual structure of the primary conditional is:

If + simple present, will + base verb

Example:

  • In case you take a look hard, you will bypass the exam.

Important points:

  • The if-clause makes use of the existing simple worrying
  • The principle clause uses will + base shape
  • A comma is used when the sentence starts with if

Changing the Order of Clauses

You can also change the order of the sentence.

Example:

  • You will bypass the exam in case you examine hard.

The that means stays the same
