1. The Formula
IF + Present Simple, WILL + Base Verb (Infinitive)
Use present simple in the if clause and will + base verb in the result clause!

Possible Future Events: If it rains, I will stay home.
Predictions: If you study, you will pass.
Promises: If you help me, I will help you.
Warnings: If you are late, you will lose your job.
Offers: If you need help, I will assist you.
3. IF vs WHEN vs UNLESS
• If you come, I will be happy. (maybe yes, maybe no)
• When you come, I will be happy. (I am sure you will come)
• Unless you come, I will be sad. (= If you don't come)
4. Word Order
• If + present simple, will + verb.
• Will + verb + if + present simple.
You can put the "if clause" first or second. The meaning is the same!
⚠️ Important Rules:
1. NEVER use "will" in the if clause!
2. Use present simple in the if clause
3. Use "will + base verb" in the result clause
