Average: 3.9 (57 votes)

The first conditional is a structure we use when we want to talk about possibilities in the present or in the future. In this lesson we will learn how the first conditional is formed and when we use it.

The structure of the first conditional

"If" Clause Main Clause
If + present simple + comma Subject + will/other modal + base verb.

If we put the main clause first then we don't need the comma.

Subject + will/other modal + base verb If + present simple.
