Examples
First Conditional: If it rains tomorrow (possible), I will take an umbrella.The speaker thinks rain is possible and has a realistic plan

- First Conditional = possible future → present simple + will
- Second Conditional = unlikely/impossible → past simple + would
- Think: How likely is this situation? This determines which conditional to use
