If: The 2nd Conditional

1. What is the 2nd conditional?

The 2nd conditional is an ‘if’ phrase for hypotheticals.

This means it is for things you can imagine, but are not true.

It uses the words ‘would’ or ‘could’.

2. How to make the 2nd conditional

The 2nd conditional is made by:

  • if clause (if + past tense) + would/could clause (would/could + base verb)

Although it is a hypothetical, the ‘if’ clause looks like a past tense.

*The base verb is the verb in its simplest form, with no ‘to’, ‘ing’, or past tense ending.

Would/could clause

If she saw him do thatshe would kill himIf she saw him do that, she would kill him.
If Peter was the bossthe company would have gone bankruptIf Peter was the boss, the company would have gone bankrupt long ago.

The ‘if’ clause can be placed at the start or at the end.

3. Overlap between 1st conditional and 2nd conditional

The 1st conditional is for cause and effect (x will make y).
The 2nd conditional is for hypotheticals (imagine x and how it makes y).

The meanings of the 1st conditional and the 2nd conditional are very close. Often either can be used.

I won’t be surprised if Brazil win the World Cup.I wouldn’t be surprised if Brazil won the World Cup.
