When to use it
Use the Second Conditional to imagine a hypothetical or unlikely situation in the present or future.
🇫🇷 Si j'avais…, je ferais…
Structure
If + Past Simple, would + base verb
If I had more free time, I would travel more often.
If I could leave tomorrow, I would go to Greece.
💡 The Past Simple here does not mean that we are talking about the past. It expresses a hypothetical situation.
The clauses can change order:
If I had more time, I would travel more.
I would travel more if I had more time.
⚠️ When the if-clause comes first, use a comma. When it comes second, you normally don't need one.
When to use it
Use the Third Conditional to imagine a different past.
The real situation has already happened and cannot be changed.
🇫🇷 Si j'avais su…, j'aurais…
Structure
If + Past Perfect, would have + past participle
If I had known it was raining, I would have stayed at home.
Reality:
I didn't know it was raining, so I didn't stay at home.
Another example:
If I had taken more water, I wouldn't have been so thirsty.
💡 Think:
Second Conditional → imaginary now / future
Third Conditional → imaginary past
