First Conditional: The Real Plan
The first conditional is the real plan: if it rains, I will stay home. A possible future with a will in the result and the present in the if.
First Conditional
The real plan
The first conditional talks about a real possibility in the future: if the condition happens, the result will follow. One plan, one will.
A real future plan
possible, and quite likelyIf it rains, I will stay home
Promises
if you do this, I will do thatIf you help me, I will help you
Unless = if not
the same plan in reverseUnless it rains, we will go out
When = if, with certainty
the plan that is sure to comeWhen you come, we will start
⚠️ If + present, will + verb. A real plan, a possible future.
The Formula
if + present → will + verb
The if-clause stays in the present — it only sets up the condition. The will lives in the result, where the future actually happens.
⚠️ Present in the if. Will in the result. Never will in the if.
Common Mistakes
Four plan slips
The plan breaks when will moves into the if-clause, when the bare verb forgets itself after will, or when both halves grab will.
If it will rain, we will cancel.
If it rains, we will cancel.
💡 The if-clause takes the present — will lives in the result.
If she comes, she will helps.
If she comes, she will help.
💡 After will, the bare verb — no -s.
I will call you if I will have time.
I will call you if I have time.
💡 The time clause stays in the present.
If you will come, I will be happy.
If you come, I will be happy.
💡 One will per sentence — and it is not in the if.

The Plan Family
Match the pieces of the plan
The first conditional is built from three pieces. Know where each one lives.
⚠️ Present in the if, will in the result — the plan never swaps them.
