Do you know how to use third and mixed conditionals?

Third conditionals and mixed conditionals

Conditionals describe the result of a certain condition. The if clause tells you the condition (If I hadn't been ill) and the main clause tells you the result (I would have gone to the party). The order of the clauses does not change the meaning.

If I hadn't been ill, I would have gone to the party.
I would have gone to the party if I hadn't been ill.

Conditional sentences are often divided into different types.

Third conditional

The third conditional is used to imagine a different past. We imagine a change in a past situation and the different result of that change.

If I had understood the instructions properly, I would have passed the exam.
We wouldn't have got lost if my phone hadn't run out of battery.

In third conditional sentences, the structure is usually: If + past perfect >> would have + past participle.

Mixed conditionals

We can use mixed conditionals when we imagine a past change with a result in the present or a present change with a result in the past.

1. Past/Present 

Here's a sentence imagining how a change in a past situation would have a result in the present.

If I hadn't got the job in Tokyo, I wouldn't be with my current partner.

So the structure is: If + past perfect >> would + infinitive.

2. Present/Past

Here's a sentence imagining how a different situation in the present would mean that the past was different as well.

It's really important. If it wasn't, I wouldn't have called you on your holiday.

And the structure is: If + past simple >> would have + past participle.

Hello everyone!
I wanted to check my level of understanding about structure "Conditionals"
Actually, This structure was too difficult for me to completely understood.
Especially that it was Mixed Conditonals
Oke, now I would write some setences with Structure "If".
1)If I hadn't studied about structer of conditionals,i wouldn't have known how to use it.
2)If i hadn't studied about structure of conditionals, i would know how to use it now
3)If i were you,i had studied about structure of conditionals.
Finally,I hope that you could check my sentences of conditionals,Thanks a lots.
I wish you met a lot of good things in your life.

Hi 0933810273,

It's good to see your practice. :)

Sentences 1 and 2 use the third conditional, which shows an unreal past (i.e., a past situation that did NOT actually happen - we are just imagining it).

Sentence 1 is grammatically correct. It means that you did study the structure, and you do know how to use it.

Sentence 2 is grammatically correct too, but the meaning is a bit confusing. It means that you did study the structure, but you do NOT know how to use it now. This can be the case if, for example, the studying made you feel more confused. Is that what you meant?

In sentence 3, 'if I were you' is normally used to give advice to someone. It's part of a second conditional (unreal present or future). It should be --> If I were you, I would study ...

I hope that helps :)

Firstly,I wanted to say "Thank You" beacasue you gave for me a lot of useful advices.And then, i wanted to talk to you about the second sentence, i thinked that you understood my mean exactly :)). By writting this sentence which conflicted with my idea. Had you not given for me these advices, i wouldn't have know about my mistake in gramma. Finally,I sincerly thank you again. I hope that you will have many good and lucky things in the life.Bye for now T

Please can I check if this is correct?

If he recorded it, he would have told me. (He didn't record it so he didn't tell me)


Hello samchua,

If I understand you correctly, a full third conditional expresses your idea: 'If he had recorded it, he would have told me'.

All the best,

Hi Jonathan

Thanks for your help highly appreciated by me

1)If I didn’t drink too much I’d feel ok
2) if I don’t drink too much I’ll feel ok
Both of the sentences express a general truth so what’s the difference???

A conditional sentence by rule expresses an unreal or real situation
Can you please show me a sentence expressing a real situation.

Best regards

Hi Andi,

The difference is in how likely these situations are. In 1, the speaker thinks this is unlikely to happen, or even impossible. He/She probably will continue to drink too much. In 2, it is possible or even likely to happen. He/She has a reasonable chance of not drinking too much.

Here are some conditional sentences showing real situations.
-- If water is heated to 100 degrees, it boils.
-- If you get 10 marks, you pass the test.

You can find more examples and explanation about these structures on our Conditionals 1 page. I hope it helps!…
