First conditional

The first conditional is a structure used to express the consequence of an action or an event.

An illustrative example is "If I get a raise I will buy a new car".

Structure

 * If ... present simple, ... will ...

The second part of the conditional has the modal verb "will".

Example: If it rains tonight I'll stay at home.

Note that the order of the two parts may be changed: I will lend it to you if I find it.
