FIRST CONDITIONAL

FIRST CONDITIONAL

The first conditional has the present simple after 'if', then the future simple in the other clause:

• if + present simple, ... will + infinitive

It's used to talk about things which might happen in the future. Of course, we can't know what will happen in the future, but this describes possible things, which could easily come true.

• If it rains, I won't go to the park.
• If I study today, I'll go to the party tonight.
• If I have enough money, I'll buy some new shoes.
• She'll be late if the train is delayed.
• She'll miss the bus if she doesn't leave soon.
• If I see her, I'll tell her.
• 
  

The First Conditional Structure

Take a look at this situation:

If I’m late tonight

This is the condition or the possible event, but this is not a complete sentence. There is some information missing. What will happen if I’m late tonight? We need another clause to explain the likely result.

Take a look at this result:

my mom will be angry

This is a complete sentence, but there is also some information missing. Why will my mom be angry? What condition, event, or situation will make my mom angry?

If I’m late tonight, my mom will be angry.

Will my mom be angry tonight if I’m late? Maybe. Probably. She may not be angry, but there is a real possibility that she will be angry. In the first conditional structure, the if-clause has a 50% or better chance of happening.

This is the first conditional sentence structure:

If + present simple, will + verb
