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.

thank you Peter M , i will explore the site to learn more .

First of all, thanks a lot for such a great material.

I have a sentence and I'm not sure if it's correct or not.
Imagine we are designing an FAQ page for a website and we want to ask people to send their questions to us, so that we can improve the page. would this sentence be grammatically correct:
"We will consider your question and add it to this page if it was in fact a frequent one."
I'm not sure if it's right to use future tense and past tense together.

Thanks in advance

Hello Mozhdeh,

I would recommend changing 'was' to 'is', but otherwise that sentence is perfect!

Thanks Kirk for your help! Much more clear now!


Hello everybody

I have a serious doubt with mixed conditionals. Could anybody tell me if we can use "should" into a 3rd conditional phrase?
e.g: If she had taken the second choice, she should have told the manger

Thanks in advance!

Hello gaullanos,

No, this sentence doesn't make sense. Please note that 'should have' is different from 'should' - 'should' refers to the present or future, whereas 'should have' refers to the past.

Depending on what you want to say, you might want to say 'If she took the second choice, she would have to tell the manager' or 'If she had taken the second choice, she would have had to tell the manager'. Does either of these make sense?

I hope this helps.
