Verbs in time clauses and conditionals usually follow the same patterns as in other clauses but there are some differences when we:
- talk about the future
- make hypotheses.
Talking about the future
In time clauses with words like when, after and until, we often use present tense forms to talk about the future:
I'll come home when I finish work.
You must wait here until your father comes.
They are coming after they have had dinner.
In conditional clauses with words like if, unless, even if, we often use present tense forms to talk about the future:
We won't be able to go out if it is raining.
I will come tomorrow unless I have to look after the children.
Even if Barcelona lose tomorrow, they will still be champions.
We do not normally use will in time clauses and conditional clauses:
I'll come home when I finish work. (NOT
will finish work)
We won't be able to go out if it rains. (NOTwill rain)
It will be nice to see Peter when he gets home. (NOTwill get home)
You must wait here until your father comes. (NOTwill come)
but we can use will if it means want to or be willing to:
I will be very happy if you will come to my party.
We should finish the job early if George will help us.

Making hypotheses
Some conditional clauses are like hypotheses, so we use past tense forms.
We use past tense forms to talk about something that does not happen or is not happening in the present:
He could get a new job if he really tried.
(= He cannot get a job because he has not tried.)
If Jack was playing, they would probably win.
(= Jack is not playing so they will probably not win.)
If I had his address, I could write to him.
(= I do not have his address so I cannot write to him.)
We use past tense forms to talk about something that we believe or know will not happen in the future:
We would go by train if it wasn't so expensive.
(= We will not go by train because it is too expensive.)
I would look after the children for you at the weekend if I was at home.
(= I cannot look after the children because I will not be at home.)
We use past tense forms to make suggestions about what might happen in the future:
If he came tomorrow, we could borrow his car.
If we invited John, Mary would bring Angela.
After I/he/she/it, we can use were instead of was:
If Jack was/were playing, they would probably win.
We would go by train if it wasn't/weren’t so expensive.
I would look after the children for you at the weekend if I was/were at home.
We use the past perfect to talk about something which did not happen in the past:
If you had seen him, you could have spoken to him.
(= You did not see him so you could not speak to him.)
You could have stayed with us if you had come to London.
(= You could not stay with us because you did not come to London.)
If we hadn't spent all our money, we could take a holiday.
(= We have spent all our money so we cannot take a holiday.)
If I had got the job, we would be living in Paris.
(= I did not get the job, so we are not living in Paris.)
If the main clause of a hypothetical conditional is about the present or future, we use a modal:
If I had got the job, we might be living in Paris now.
(= I did not get the job so we are not living in Paris now.)
If you had done your homework, you would know the answer.
(= You did not do your homework so you do not know the answer.)
If the main clause is about the past, we use a modal with have:
If I had seen him, I would have spoken to him.
(= I did not see him so I did not speak to him.)
You could have stayed with us if you had come to London.
(= You could not stay with us because you did not come to London.)
If you had invited me, I might have come.
(= You did not invite me so I did not come.)

Why is it not "Barcelona loses" in your example? Why is the verb plural?
Hello m6769,
The names of institutions and organisations can often be either singular or plural, so you can say 'Barcelona loses' or 'Barcelona lose'.
Some other examples of this include the army, the police, the government, the European Union, the judiciary, the media and the BBC.

Hello,
If a "would have V3" sentence is used alone, should we take it as a sentence about an unreal past situation?
For example ... "the landscape would have been open" ... does this sentence mean that ... in fact landscape was not open in the past?
Thanks a lot.
Hello Ilter,
It certainly could be talking about an unreal past situation, and I'd even go so far as to say it probably is talking about an unreal past situation, but what exactly it means really depends on the context. The context and the verb forms make meaning together.
If you can give us the context, then we can tell you more.
All the best,

Hello Kirk,
The complete paragraph is ...
"Walking back through the menhirs, Agogué explained while the Alignments are reasonably well preserved, both nature and humans have altered the appearance of the site over time. When the Alignments were constructed, the landscape would have been open, without the trees that now divide and flank the sections, and the sea would have been further away. And in the past 6,000 years, some of the menhirs have toppled over – including one last year."
In this context, I think that it does not talk about an unreal past ... would "might have been" be more correct here? What the meaning here "would" adding to the context?
Thanks a lot,
Best wishes
Hello Ilter,
Thanks for giving the full context -- that's much clearer now.
This is the use described on our 'will have' and 'would have' page in sentences such as:
In a case like this, the speaker has good reasons for their belief (for example, she knows her father always finishes at 5:00), but not direct evidence (she hasn't seen him leave work). The speaker is imagining a situation that they haven't witnessed but which seems likely due to some evidence. It could be their knowledge of that person's typical behaviour, or it could be some other evidence.
In the passage you ask about, the writer supposes that the landscape was open in the past -- they probably have some archaeological or historical evidence to support this idea and are fairly certain about it -- but obviously they didn't witness it themselves.
Does that make sense?
All the best,
Kirk

Yes got it ... thank you so much Kirk ... best wishes
Hey, I hope it's still okay to comment, I have two examples about which I'd like to know more please!
first example: *boy comes to a girl's house to ask her dad* "Hey, is she here? I promised her I'd see her before I left"
second example: *they don't want him to go outside while there's danger* "Nobody would want him to leave the safety of the house until the criminal was caught"
Please explain these two to me! Maybe with a sort of model/format/structure and also the name of this?
And I couldn't find anything on the web with this example, especially with before/until, and would + verb so if you could talk about this too if there's anything to it.
Thank you in advance!
Hi aa223,
Sure, no problem. You can think of example 1 as reported speech (i.e. indirect speech). The boy may have said to the girl, "I promise I'll see you before I leave". Some time later, the boy tells the girl's dad what he promised her earlier, so it all shifts back into the past (promise --> promised; I'll see --> I would see; leave --> left). You can read more about this on our Reported Speech 1 page (linked).
In example 2, "would" and the use of the simple past "was caught" frame the situation as an imagined or hypothetical one, rather than one that is realistic or bound to happen. It suggests that the speaker is not confident or certain that the criminal will actually be caught. Saying "Nobody would want him ..." (rather than "Nobody wants him ...") suggests that the speaker has not actually gone around and asked everybody what they want, but is supposing or assuming what they want.
I hope that helps to make sense of it.

Hi dear team. I was wondering if you could help me identify what kind of sentence the following one I saw in a movie. I mean, I know that the zero conditional is used with present simple in both clauses but I don't know if we can use zero conditional with both clauses in simple past. And also I know that the second conditional is used for hypothetical situations and has a Modal verb like would and will. My question is what kind of sentence is this one? : "If somebody said it was a happy little tale, if somebody told you I was just an average ordinary guy, not a care in the world, somebody lied". Thank you so much.
Hello David,
When we're not speaking about an imaginary or unreal situation (as in a second or third conditional), the verb tenses we use in sentences with 'if' have their 'normal' meanings -- in other words, the present refers to the present and the past to the past.
That's the case for the sentence 'If somebody said it was a happy little tale, if somebody told you I was just an average ordinary guy, not a care in the world, somebody lied'. Without knowing more about the situation, it's hard to work exactly what is meant by this, but basically the speaker is saying that whatever another person said about them isn't or wasn't true.
Does that make sense?
All the best,
Kirk

Thank you so much dear Kirk for your help.
So is it possible to classify the if clause in simple past and the main clause in simple past in a specific category? I mean do you think that sentences like: 'if someone called me, I didn't notice it' or 'if I came late, it wasn't my fault' are a kind of zero conditional with both clauses in simple past or do they belong to a different category?
Thank you so much.
And regarding the sentence from the previous comment do you think it is a kind of indirect question? I mean: (' did somebody say it was a happy little tale? Well, somebody lied = 'If somebody said it was a happy little tale, somebody lied').
Thank you so much for your help.
Hello David Araque,
The so-called 'zero', 'first', 'second' and 'third' conditional labels were created by teachers as a way to help students make sense of some common patterns. But the truth is, 'if' sentences can be used with any verb tense that makes sense. Of course, what makes sense isn't always easy for students to discern, and so that's why we have these labels. But, as you've discovered, other combinations are possible.
If you think about it, the tenses in zero and first conditionals are 'normal' uses of the verb tenses. The same is true of second and third conditionals, too, because the use of the past to talk about unreal situations is a use of the past tense that also occurs in other structures (e.g. 'I wish it were raining now'); we just don't typically think of these uses. So really all the tenses we use in 'if' sentences are normal uses of the verb tenses that exist in other situations too.
I wouldn't call the sentence in a question a zero conditional, personally. It's two past simple verbs used to talk about a condition in the past. But if coming up with some name for this structure helps you remember it, then by all means, go ahead -- just know it will be your own creation.
Yes, 'Did somebody say (that) it was a happy little tale?' has the structure of an indirect question. But if you combine it with 'somebody' lied, the indirect question is embedded within the larger 'if' sentence.
Hope that helps.
All the best,
Kirk

Thank you so much dear Kirk for your explanation. It really helped me a lot.
Can you please shed light on the proper structure of this sentence.
"He promised to come when he was/is done at work"
Please which is correct to use between "was" or "is"?
Hello Aryin,
It depends. If the speaker thinks the man is still working when the speaker says this, then 'is' is the correct form. But if the speaker thinks the man already finished his work at the time of speaking, then 'was' is the correct form.
All the best,

Sir,
In your above-mentioned example
‘We would go by train if it wasn't so expensive.
(= We will not go by train because it is too expensive.)
I would look after the children for you at the weekend if I was at home.
(= I cannot look after the children because I will not be at home.)
- I used to write e.g. ‘We would go by train if it weren’t (!) so expensive.’
‘I would look after the children for you at the weekend if I were (!) at home.’
Could you, please, explain it to me why you used another grammatical form?
Thank you in advance.
Hello Helena-Victoria,
In 'if' clauses talking about an unreal situation, both 'was' and 'were' are correct forms of the verb 'be' for both first-person singular subjects ('I') and third-person singular subjects ('he', 'she' or 'it').
Many years ago, the only correct form for such situations was 'were', but now in all but very formal situations, 'was' is also accepted. If it's easier for you to remember 'were', then by all means use it -- it is perfectly correct!
All the best,
Kirk

Hi Nevı,
It could refer to the present or the future :)
We would need to know the context in which this is said to know which timeframe is intended.

Hello Nevi,
Yes, it looks as if you understand this correctly. Good work!

Hello Nevı,
In your example when is a conjunction.

Hello Gendeng,
The sentence implies that the result is not known, so you would say this before you learn the result. Once the result is known (and you didn't win!), you would say 'If I had won... I would have...'

Hi Nuro,
Both had more time and had had more time are possible here.
We use the past perfect (had + verb3) when we are talking about a particular situation at a particular time:
In other words, 'had had' describes a specific instance of not having time, not a general situation.
We use the past simple (verb2) when we are making a non-time specific statement:
In other words, 'had' describes something which is generally true of the speaker's life - they never have time, and the presentation is not as good as it might be because of this.

Hello Aglaia,
Yes, you can use a range of future forms in the main clause. Will indicates a conditional prediction; going to, a conditional plan; present continuous, a conditional arrangement. Other modals are also possible, showing conditional probability, possibility, advice etc.

Hello Samin,
'furniture' is an uncount noun and so 'there is' is the correct verb form here.

Hello Risa warysha,
All of the words (if, when and as) are possible in this example, but the meaning changes.
If tells us that you are not sure whether or not the man was working yesterday.
When tells us that you know he was not working, but are not sure whether or not he was ill.
As tells us that you are drawing a conclusion (that he was ill) from the fact that he was not working yesterday.

Hi gsg238,
The first sentence is actually the correct one :)
In the second sentence, we can't say if you had came because after had, it must be the past participle form of the verb (come = past participle; came = past simple). This is a past perfect structure (see this page for more examples and explanation).
In the third sentence, the subject (you) is needed. It can't be omitted from the if-clause. We also need to add if.
Alternatively, we can use this more formal form without if and with an inversion: You could have stayed with us had you come to London.
Does that make sense?
Best wishes,
Jonathan
Hello Tim,
Yes, that's right. When speaking about the past you could also use the past perfect or the past continuous, and when speaking about the present, the present continuous is also possible, but in these cases they are used in the normal way -- that is, not like the use of the present simple to speak about the future, for example.
All the best,
Kirk

Hello Harry de ZHANG,
Both sentences do refer to a hypothetical present time. The difference between the two sentences lies in the modal verb. 'would be living' states that in that hypothetical situation (in which I got the job -- in reality I did not get the job), we are definitely now living in Paris. 'might be living in Paris now' states that in that hypothetical situation, perhaps we are living in Paris and perhaps we are not.
All the best,
Kirk

Hello Harry de ZHANG,
I'm glad that helped you!
And thanks for pointing out that error to us -- you are right and I have fixed the error.
