Definition of First Conditional
The first conditional indicates something that may happen in the present or future. It has a two-clause structure. This includes an if clause and the main clause.
A comma usually separates the two clauses if the if clause precedes the main clause. The example below illustrates the comma necessity.
- If I win the contest, I will be rich.
When the main clause appears first, there is no need for a comma. The example below shows the lack of a comma.
- I will be rich if I win the contest.
Structure of the First Conditional Sentences:
The first conditional uses a different verb form in each clause. To construct the if clause, you would write if + subject + simple present verb tense. To construct the main clause, you would write subject + will + verb.
First Conditional Form: If + Simple Present, Subject + will/won’t + Verb.
You can reverse the order of the clauses. If the “if” clause comes first, a comma is usually used. If the “if” clause comes second, there is no need for a comma
- I will stay at home if it rains.

How and When to Use the First Conditional
Conditional sentence type 1 is used to talk about things that are possible in the present or the future.
Examples of conditional sentences of type 1:
- If it rains, I will stay at home.
- If I wake up late, I will miss the bus.
- And, if it‘s sunny, we‘ll go to the park.
- If Juan leaves, Paula will be sad.
We use “may” or “might” to say that a future event is possible but not definite.
For example:
- If you need someone to help you move, I might be able to help.
- If it’s a sunny day tomorrow, we might have a pool party.
Sometimes we use “be going to” instead of “will” in the main clause. This is done to emphasize a certain result.
For example:
- I’m going to give you twenty pounds if you fix my computer for me.
- I’m going to stay for the weekend, if you like.
- If you are not ready, I‘m going to go out without you.
