First Conditional

The first conditional (also called conditional type 1) is a structure used for talking about possibilities in the present or in the future. This page will explain how the first conditional is formed, and when to use it.

The structure of a first conditional sentence

A first conditional sentence consists of two clauses, an "if" clause and a main clause:

if clause
main clause
If you study hard,
you will pass the test.

If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:

main clause
if clause
You will pass the test
if you study hard.

We use different verb forms in each part of a first conditional:

if clause
if + subject + simple present verb
main clause
subject + will + verb

Using the first conditional

The first conditional is used to talk about things which are possible in the present or the future -- things which may happen:

If it's sunny, we'll go to the park.
Maybe it will be sunny -- that's possible.
Paula will be sad if Juan leaves.
Maybe Juan will leave -- that's possible.
If you cook the supper, I'll wash the dishes.
Maybe you will cook the supper -- that's possible.
