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 jiyi

Thank you -- we also wish you a happy 2019! Although I wouldn't say this sentence is incorrect, I think it would be clearer if it were changed to one of the following:

If the cost of transportation were lower, the merchandise would obviously become less expensive and more people could afford it.
If the cost of transportation is lower, the merchandise will obviously become less expensive and more people will be able to afford it.

I hope this helps you.

All the best

Sorry sir just a little edit If i had told

That sentence about mixed condition if it was wrong , could you kindly correct it , " if i told her about my love we would be getting married this year

Hello ramy brava,

That does not seem a logical sentence to me.

The phrase 'we would be getting married this year' suggests that a plan would be already in place; it means something like 'our wedding would already be planned'. However, the phrase 'if I told her' refers to a hypothetical future. This means that the time order is incorrect: there could not be a wedding plan already in place before you tell her about your love.

There are various ways to change the sentnece, but it depends what you want to say. For example:

If I had told her about my love, we would be getting married this year.

If I told her about my love, we would get married this year.

Thanks sir , then the sentence if i had told , would be getting matried ,, is correct

Kindly i want more sentences about mixed conditional to be more clearly sir please ,

Hello ramy brava,

'Mixed conditionals' are simply conditional sentences which have two different time references: one for the if-clause and a different one for the result-clause.

thank you so much, teacher Kirk! That clears everything for me about these sentences :)

Dear,teacher Kirk. I am sorry to bother you again. I forgot to ask the third sentence ( 'If I kissed the girl, I will have to apologize to her'). It isn't indicate a hypothetical situation, is it? I mean : does the sentence gives you impression that ' I did kiss the girl , or at least, I am convinced that I did kiss the girl in the past , and now I regret it and I realize I must then apologize to her' ? Thank you so much again.

Hello again jiyi,

This third sentence would not be correct in most situations. If the if-clause refers to a hypothetical situation, as it seems to do here, the other clause needs some kind of conditional verb (e.g. 'would'). For example, 'If I kissed the girl, I would have to apologise'.

If, however, the speaker is speaking about the past, for example, admitting that they possibly don't remember their actions, then this sentence could be grammatically correct. It would mean something like 'I don't think I kissed the girl, but if I did, I will have to apologise to her'.

All the best,
