Here is a post about the different types of Conditionals in English and a brief description of each one. I hope you find it useful.
Conditionals are sentences with two clauses – an “if clause” and a main clause – that are closely related. Conditional sentences are often divided into different types.
We use the zero conditional to talk about things that are always true.
- If you heat water, it boils.
- When the sun goes down, it gets dark.
- It lights up if you push that button.
The present simple is used in both clauses.
We use the first conditional when we talk about real and possible situations.
- I’ll go shopping on the way home if I have time.
- If it’s a nice day tomorrow we’ll go to the beach.
- If Arsenal win they’ll be top of the league.
In first conditional sentences, the structure is usually if + present simple and will + infinitive. It’s not important which clause comes first.
The second conditional is used to talk about ‘unreal’ or impossible things.
- If I won a lot of money I’d buy a big house in the country.
- Where would you live if you could live anywhere in the world?
- If you didn’t smoke so much you’d feel a lot better.
The structure is usually if + past simple and would + infinitive. It’s not important which clause comes first.
Look at the difference between the first and second conditionals.
- In January: If it snows tomorrow I’ll go skiing. It might snow tomorrow.
- In August: If it snowed tomorrow I’d go skiing. It almost certainly won’t snow tomorrow.
NOTE: Although many conditional sentences use if + will/would, conditional sentences can also use other words instead of ‘if’ – e.g. ‘when’ ‘as soon as’ ‘in case’ Other modal verbs can be used instead of ‘will/would’ – e.g. ‘can/could’, ‘may’ ‘might’.
Third conditional sentences describe the past. They describe something that didn’t happen.
- If I’d studied harder at school I would have gone to university.
He didn’t study very hard and he didn’t go to university.
- We wouldn’t have got lost if you hadn’t given me the wrong directions.
She wasn’t given the correct directions and she didn’t find her way.
- She might have finished the exam if she’d had more time.
She didn’t finish the exam and she didn’t have more time.
In third conditional sentences, the structure is usually if + past perfect and would + perfect infinitive (e.g. have done). It’s not important which clause comes first.
Notice that other modal verbs can be used instead of ‘would’ (e.g. ‘could’, ‘might’ ‘may’)
In mixed conditional sentences, the time in the ‘if’ clause is not the same as the time in the main clause. There can be various combinations.
- If he’d gone to university he might have a better job.
He didn’t go to university (past)
He doesn’t have a very good job. (present)
This sentence shows the present consequences of a past action.
- If I’d won the competition I’d be going to Florida next week.
She didn’t win the competition (past)
She isn’t going to Florida (future)
This sentence shows the future consequences of a past action.
- If he didn’t have to work tomorrow he wouldn’t be so miserable today.
He has to work tomorrow (future)
He’s miserable. (present)
This sentence shows the present consequence of a future event.
