Conditional Sentences (Types 0, 1, 2, 3)

Conditional sentences express that the action in the main clause can only happen if a certain condition is fulfilled. There are four main types of conditionals in English.

1. Type 0 – General Truth

Form: If + present simple, present simple
Use: For general truths and scientific facts.
Example: "If you heat water to 100°C, it boils." "If it rains, the grass gets wet."

2. Type 1 – Real Future

Form: If + present simple, will + base verb
Use: For possible situations in the future.
Example: "If I study hard, I will pass the exam." "If it rains, we will stay at home."
Variations: can/may/might/should + base verb in main clause

3. Type 2 – Unreal Present

Form: If + past simple, would + base verb
Use: For imaginary or unlikely situations in the present/future.
Example: "If I had a million dollars, I would travel the world." "If I were you, I would study more."
Note: Use "were" for all subjects in formal English.

4. Type 3 – Unreal Past

Form: If + past perfect, would have + past participle
Use: For impossible past situations (regrets).
Example: "If I had studied harder, I would have passed the exam." (But I didn’t study hard, so I failed.)

5. Mixed Conditionals

Sometimes we mix type 2 and type 3:
– If + past perfect (type 3), would + base verb (type 2): "If I had studied medicine, I would be a doctor now."
