When to use it

First conditional describes a real and likely situation in the future. The if-clause states the condition using present simple; the result clause uses will + base verb.

If it rains tomorrow, we will cancel the trip.

The condition is genuinely possible — there is a real chance of rain.

Form

The if-clause can come first or second. When it comes first, separate the two clauses with a comma. When the result clause comes first, no comma is needed: "She will pass the exam if she studies hard."

Examples

• If you leave now, you will catch the last bus.
• I will call you if I hear any news.
• Will you be upset if she does not come?

Common mistakes

• Using will in the if-clause: "If it will rain" is wrong. The if-clause always uses present simple ("If it rains").
• Confusing first conditional (real possibility) with second conditional (unreal/unlikely situation). "If I win the lottery" uses first conditional only if you genuinely believe you might win.
