Third conditionals and mixed conditionals

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.

Third conditional

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’)

Mixed conditionals

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.

Not to forget, I wanted to ask you about the passive construction in the 2nd Conditional which you talked about. Can we use inversion there or does it require "were to" to sound good?
For example, can we say: "Were I asked this question, I would tell the truth."
Or, is the following the only correct option:" Were I to be asked this question, I would tell the truth."

Once again, thank you very much for your time!

Hello Kelly S,

Both 'Were I asked...' and 'Were I to be asked...' are possible here. This construction can be used with other passive forms:

Were he given the chance...

Were he to be given the chance...

The form with 'to' is more common, I would say, though I do not have any data on this.

Thank you very much for you quick reply!

I have one more question, related to inversion. It has to do with the use of "as" before an auxiliary to show that the same is true for somebody else.
Eg. Italy produces excellent wines, as does Spain.
She is tall, as is her mother.

Is inversion always required here or is it optional?
That is, can we also say:
Italy produces excellent wines, as Spain does.
She is tall, as her mother is.

Thank you very much!!

Hello Kelly S.

Both versions (with and without inversion) are correct. I think the version with inversion is more common but neither is incorrect.

Hello,

'If the water has reached the town, then the last flood barrier has failed'

I know that there are two rules for creating conditionals one of which is ''an if-clause always happens first''

Does the sentence above satisfy the rule?

Many thanks

Hello MCWSL,

The condition must precede the result as a straightforward issue of logic rather than grammar.

That sentence is a little unusual in that it has two present perfect forms but it is quite consistent and correct. The meaning here is not immediately clear, however. It does not mean that first the water reaches the town and then the barrier fails as the second clause really refers to our awareness of the failure. In other words, the second clause really tells us 'then we can conclude that the last flood barrier has failed' or 'then we know that the last...'

Hello Kirk could you please explain these conditionals.
If I were you, I would have not done this.
If i were you, I would not do this.

Hello Asgharkhan8,

The second sentence is in the second conditional and is a common way of giving advice. The first sentence is a mixed conditional and speaks about an imaginary or unreal past situation. Please note the word order is slightly incorrect: it should be 'I would not have done'.

All the best,
