❓ Frequently Asked Questions
Q1.What is the difference between Zero Conditional and First Conditional?▼
Zero Conditional is for 100% true facts (If you heat ice, it melts). First Conditional is for real possibilities in the future (If it rains tomorrow, I will stay home).
Q2.Can I use 'when' instead of 'if' in First Conditional?▼
Yes, but 'when' means you are sure the condition will happen. 'If' means it's possible but not certain. Example: 'When you arrive, call me' (I know you will arrive). 'If you arrive, call me' (I'm not sure).
Q3.What tense do we use in First Conditional?▼
We use Present Simple in the 'if' clause and 'will + base verb' in the result clause. Never use 'will' in the if clause!
