'will' and 'would'

Level: beginner

We use will:

  • to express beliefs about the present or future
  • to talk about what people want to do or are willing to do
  • to make promises, offers and requests.

would is the past tense form of will. Because it is a past tense, it is used:

  • to talk about the past
  • to talk about hypotheses (when we imagine something)
  • for politeness.


We use will to express beliefs about the present or future:

John will be in his office. (present)
We'll be late. (future)
We will have to take the train. (future)

We use would as the past of will, to describe past beliefs about the future:

I thought we would be late, so we would have to take the train.


We use will:

  • to talk about what people want to do or are willing to do:

We'll see you tomorrow.
Perhaps Dad will lend me the car.

  • to talk about typical behaviour, things that we often do (because we are willing to do them):

We always spend our holidays at our favourite hotel at the seaside. We'll get up early every morning and have a quick breakfast then we'll go across the road to the beach.

We use would as the past tense of will:

  • to talk about what people wanted to do or were willing to do in the past:

We had a terrible night. The baby wouldn't go to sleep.
Dad wouldn't lend me the car, so we had to take the train.

  • to talk about typical behaviour, things that we often did (because we were willing to do them) in the past:

When they were children they used to spend their holidays at their grandmother's at the seaside. They'd get up early every morning and have a quick breakfast. Then they'd run across the road to the beach.

Promises, offers and requests

We use I will or We will to make promises and offers:

I'll give you a lift home after the party.
We'll come and see you next week.

We use Will you … ? or Would you … ? to make requests:

Will you carry this for me, please?
Would you please be quiet?

Hypotheses and conditionals

We use will in conditionals to say what we think will happen in the present or future:

I'll give her a call if I can find her number.
You won't get in unless you have a ticket.

We use would to make hypotheses:

  • when we imagine a situation:

It would be very expensive to stay in a hotel.
I would give you a lift, but my wife has the car today.

  • in conditionals:

I would give her a call if I could find her number.
If I had the money, I'd buy a new car.
You would lose weight if you took more exercise.
If he got a new job, he would probably make more money.
What if he lost his job? What would happen then?

We also use conditionals to give advice :

Dan will help you if you ask him.

Past tenses are more polite:

Dan would help you if you asked him.

Hello AsahiYo20,

If you replaced 'is not likely to' with 'won't', the sentence wouldn't make a lot of sense because 'won't' suggests you are sure, but the second half suggests that you aren't. It would be better to leave it as is.

It's possible to replace 'wouldn't' with 'won't', but it would only be appropriate in a different context. If you would like to explain the context, we can give you more specific advice on that.

For sentence 2, yes, you could, though as with my second comment above, only in a specific situation that's different from situation you would use 'would not' in.

If you have any other questions similar to these, could you please explain the situation or context more? It's difficult for us to give a quick answer without knowing more.

Thanks in advance.

All the best,

Actually I saw these sentences when I was looking up the dictionary, so I am not sure about the exact context. But I would be grateful if you could further explain the difference.

1. 1st Sentence - If this is an answer to a question of whether I will do something in the future or a company will adopt some measure, would the use of “wouldn’t rule out” be appropriate in this sentence? Actually I can’t think of any context in which “won’t rule out” would be a better choice, because I think the degree of conviction would be too strong in this sentence. Could you give me some examples of “won’t” in this context?

2. 2nd Sentence - Is “would not” more likely when giving advice to people? Am I correct to say that “is not” would be more likely if the sentence talks more generally about the problems with taking action without knowing all the facts?

Thanks teacher.

Hi AsahiYo20,

I'll copy the sentences here for easy reference.

1a. It's not likely to happen but I wouldn't rule out the possibility.

1b. It's not likely to happen but I won't rule out the possibility.

You're right that 1b is more definite than 1a. For example, a politician might say 1b about whether or not they will run for election. 1b sounds like an official declaration of the speaker's intention. 1a, on the other hand, is a hypothetical statement (i.e. without any immediate practical implications). So, as Kirk mentioned, which one we would use is really dependent on the context.

2a. Taking action without knowing all the facts would not be a prudent course.

2b. Taking action without knowing all the facts is not a prudent course.

Yes! Both 2a and 2b may be giving advice to someone about what not to do. Using would makes the advice less direct but more polite. Yes, 2b may be more general. Again, though, it's hard to say without the context :)

I hope that helps.

Best wishes,

When I was looking up the meaning of "ill afford", I saw this explanation:
"If you say that someone can ill afford to do something, or can ill afford something, you mean that they must prevent it from happening because it would be harmful or embarrassing to them"

I notice that it uses "...would be harmful...". Could I say "will be harmful" instead?

Thanks a lot teachers!

Hello PabloTT,

The author uses would here because the situation they are describing is not a real situation but is hypothetical.

Will would be used if the situation were real. It would not just be describing something in general or theoretical terms, but would be describing an actual situation where there was a possibility of a choice being made.



The LearnEnglish Team

Hi Sir,

Thanks for your reply. Am I correct to say that it is hypothetical in the sense that when writing this sentence, the author is not referring to any particular situation in the real world?

Hello again PabloTT,

Yes, that's right.

I would like to ask two questions. Grateful if you could help.

1. "He wouldn't apologize. He knew he was in the right" - Does the use of "wouldn't" instead of "didn't" convey an extra meaning that he was unwilling to apologize?

2. "With more emphasis on biliteracy, failing to be proficient in English would compromise academic performance and undermine the chance of getting into a post-secondary institution" - Could I use "compromises" or "will compromise" instead of "would compromise"?

Hello cms10,

Yes, that's right: 'wouldn't' means he was unwilling in sentence 1. The alternatives you ask about in sentence 2 might work or might not -- it depends on the context. If, for example, the context is one in which you are speaking of a hypothetical situation, 'would' would probably be more appropriate.

All the best,


The LearnEnglish Team

Thanks for your reply teacher!

Regarding Sentence 2, if it is talking about a general social phenomenon, would "compromises" or "will compromise" be better?
