The First Conditional


The 'First Conditional', also known as the 'Conditional Type 1', is an English grammar structure used to discuss possibilities and probable situations. This structure often includes a condition, expressed in the simple present tense, and a potential result, expressed in the simple future tense. With this tutorial, we'll delve into its structure, usage, and some examples to make your understanding of the First Conditional concrete and comprehensive.

How to Formulate the First Conditional

The First Conditional is primarily made up of two clauses, the 'if' clause (the condition), and the 'main' clause (the result). Each clause can come first or second in the sentence – the choice depends on what you want to emphasize.

The general formula for the First Conditional is:

  • If + Simple Present Tense, + Will + Base Form of Verb

or alternatively:

  • Will + Base Form of Verb, + If + Simple Present Tense


  • If it rains, we will stay at home.
  • We will stay at home if it rains.

Usage of the First Conditional


One of the most common uses of the First Conditional is to make predictions that are likely to happen in the future if a specific condition is fulfilled.


  • If I finish work early, I will play soccer.
  • If you don't hurry, you will miss the train.

Threats or Warnings

The First Conditional is often used to make threats or warnings, where the speaker predicts a negative result if some condition is met.


  • If you touch that electric wire, you will get a shock.
  • If you don’t stop making that noise, I will call the police.


First Conditional is also used for giving advice by suggesting a particular outcome if a certain action is taken or not taken.


  • If you study well, you will pass the examination.
  • If you don’t rest now, you will feel tired later.

Important Rules to Remember

Order of the Clauses

The 'if' clause can come before or after the main clause. However, the order often changes the emphasis of the sentence. If the sentence starts with the 'if' clause, use a comma to separate the two clauses. No comma is needed if the sentence begins with the main clause.


  • If you study hard, you will pass the exam. (emphasis on the condition)
  • You will pass the exam if you study hard. (emphasis on the result)

Using 'will' in the 'If' Clause

As a general rule, avoid using 'will' in the 'if' clause. The 'if' clause talks about a condition, not a future prediction, so it usually stays in the simple present tense.

Incorrect example:

  • If I will go to the party, I will take a gift.

Correct example:

  • If I go to the party, I will take a gift.

Do not use Unless instead of If Not

If you use 'unless' instead of 'if not', you need to be careful with the structure of your sentence. 'Unless' is used to mean 'if not' only in positive sentences, not negatives (when the main clause is negative).


  • Unless you study hard, you won't pass the test. (Correct)
  • Unless you don’t study hard, you will pass the test. (Incorrect)


The First Conditional is a crucial grammar structure in English, allowing you to express future consequences based on a present condition. It might seem challenging at first, but with ample practice and clear understanding, you will be able to use it fluently. Always remember to construct your sentence well, watch the tense in your 'if' clause, and be wary of your clause's placement for added emphasis. Happy practicing!
