First Conditional

English Grammar


When we are thinking about a possible situation in the future, we use:

If + Present verb, future verb

This structure is common when talking about possible plans, promises, warnings, threats or for persuading someone. We are predicting a likely result in the future if a condition is fulfilled.

If + Simple Present, Will / Won't ...

Notice how we use a comma after the present tense clause.

We can also reverse the order and use:

Future Verb + If + Present Simple

Notice how the comma is not necessary with this word order.

Modal Verbs in First Conditional

Normally WILL is used in the main clause of first conditional sentences. However you can also use the modal verbs MAY, MIGHT and COULD when something is a possible consequence (and not a certain one) in the future.
