First Conditional: Conditional Sentences Type 1 Rules & Examples

First Conditional! Learn how to use Conditional Sentences Type 1 (Present or Future Real Conditional) with structure, usage and example sentences.

What Is the First Conditional?

  • Like a zero conditional, a first conditional sentence consists of two clauses, an “if” clause and a main clause. We use different verb forms in each part of a first conditional:

First Conditional Form: If + Simple Present, Subject + will/won’t + Verb.

First conditional examples:

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.

  • 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.

  • We use ‘may‘ or ‘might‘ to say that the 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.
