Grammar explanation
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 again Shetu Yogme,
I think in this case the past perfect is better: If I hadn't been in the middle... would have been happy...
You could argue that the speaker is still in the middle of the meeting - it has not finished at the time of speaking - and so the condition is ongoing. However, this is irrelevant to the action in the main clause. What mattered was that the speaker was busy at the time of the request, not whether or not the meeting continues.

Hello Peter,
I have also the same opinion. The correct sentence should be:
I picked up this sentence from the following website:

I think some sources in the Internet have a plenty of errors in terms of grammar and logic in the content they offer on English Grammar.

Dear Trainer,
Could you please write 3-5 sentences (using conditionals: third and mixed) as an example, which we typically use in our daily conversations?
Hello Farhat-R,

Thank you so much sir.
Hello, I have a question.
In the Mixed conditional (present/past) using the verb "to be," can I use "was" in the first and third person singular?
For example:
"If she wasn't diabetic, she would have eaten pasta."
Or "If I wasn't a good person, I wouldn't have helped you."
Or should I use "were" instead of "was" as in the Second conditional?
Thank you.
Hello JScar92,
You can use either was or were here without any difference in meaning.

Thanks Peter for your reply.
Hello JScar92,
Were is formal and preferred, and in informal situations it is absolutely OK to use was.
Shetu Yogme.
Thank you Shetu Yogme for your comment.
