Modal verbs

Learn about modal verbs and their different meanings and do the exercises to practise using them.

Level: beginner

The modal verbs are: 

can
may
must
shall
will
could
might

should
would

We use modals to show if we believe something is certain, possible or impossible:

My keys must be in the car.
It might rain tomorrow.
That can't be Peter's coat. It's too small.

We also use them to do things like talk about ability, ask permission, and make requests and offers:

I can't swim.
May I ask a question?
Could I have some tea, please?
Would you like some help?

Hello.I would like to ask if it is wise to learn by heart all the modal verbs. Thank you.

Hello Mina Mantzorou

We use many modal verbs quite often, so I would say that it's important to recognise them and know their main uses and meanings. It's probably better to concentrate on just a few modals at a time, as each one has different meanings and uses and it can take time to learn to really use them.

All the best

Hello!1) i would have been late if mr Neal did not drive, 2) i am happy that you would come if i would let you cook dinner . are these sentence correct? i think they might also make the same sense witten in the following way: 1) i wuold have been late if Mr Neal had not driven; 2) i am happy that you would come if i let you cook dinner. Thanks.

Hello rosario70,

The first sentence is rather odd. If you use did not drive then you are taking about Mr. Neal's general ability (that he knows how to drive) rather than what he did in a particular case. Therefore had not driven (talking about what Mr. Neal did on one particular journey) makes more sense.

In the second sentence you should use if I let rather than if I would let. We very rarely use would or will in the if-clause of conditonal sentences.

Hello. Some of my colleagues, teachers of English, say that in the following sentence, "must" is wrong and they use "have to", or "need to". Please, which one is correct? In England, most people must work until they are 67. Thank you.

Hello Ahmed Imam,

The sentence describes an external obligation rather than something we impose on ourselves, so 'have to' is a more natural choice. However, the distinction between 'must' and 'have to' is a subtle one and I would not say that 'must' is wrong here.

Hello. Can you please help me construct a sentence in following situation - I have been invited to an event in the future (2 weeks from now). I didn't immediately rsvp because I didn't know if I was going to be in town on that date. Now I know that I am in town so I write to the person who invited me the following - Sorry for the delay in getting back. But there was a possibility that I could have been out of town on that weekend but not anymore. So I will attend the event. Is the use of modal verb could have been - correct? Normally modal verb + have is only used for past possibility whereas here I am trying to communicate that there was something possible in the future but not anymore. Greatly appreciate your response.

Hello autumn

I'd say 'Sorry for the delay in getting back to you. There was a chance I was going to be out of town that weekend, but now I know I will be here. I would love to attend.' Maybe I've been too enthusastic at the end by saying 'I would love to attend' but you can change that to what you suggested.

You are right about 'could have'. Here it's a case of the future in the past (see the section called The future in the past on this page). We often use 'would' here, and you could say 'would' instead of 'was going to', but that's what came first to mind. There's no real difference in meaning between 'would' and 'was going to' in this case.

I hope you enjoy attending the event!

All the best

Sir, I have learned a rule that states - Can refers to a theoretical possibility while may refers to future possibility. Such as... 1.I think you can win the competition. 2.There can be cold at night so take your jacket. May I tell... I think you may win competition. What is the difference. Thanks in advance.

Hello AminulIslam.,

In some contexts the difference between can and may is very slight. For example:

I think you can win the competition. [it is possible]

I think you can win the competition. [there is a chance of this]

 

The first sentence could mean 'it is possible because you are allowed to enter', a different meaning to the second sentence. But it could also mean 'it is possible because you are good enough', which is very similar to the second sentence. The context is key here.

 

The other sentence is not correct as it stands. We would say this:

It can be cold at night so take your jacket. [low temperatures are possible]

It may be cold at night so take your jacket. [there is a chance of low temperatures]

Sir, You may know this. You must know this. I think these sentences may have different meanings depanding on the context can't they ? In one context these sentense can mean that a person is saying on logical conclusions or bases that the other person probably knows this. While in the other one they can mean that a person is suggesting or giving advice to the other person that they should definately know this or they can or could know it if they want to. and I think sometimes to erase out this confussion we say something like "you may be aware of this or you must be knowing this" as these sentences have an only particuler meaning. what is your take on this ?

Hi SonuKumar

Yes, the context is key to understanding these sentences. English modal verbs (like 'may' and 'must') are used to mean different things in different contexts and so without knowing the context for these two statements, I can't say for sure what they mean. The sentence with 'must', for example, can mean 'You really need to know this' or 'I can't believe that you don't know this' (meaning I think you do know it).

Hello Adya's

Modal verbs in English are used in so many different ways that it's difficult for a statement like the one you mention to be accurate in all circumstances. Could you give a specific example? We could help you out with a specific case, but I'm hesitant to make any generalisations for fear of missing something out.

Pls I Need More Clarity On This Rule Of Auxiliary Verb I Came Across While Studying: Auxiliary Verbs In Simple Present Tense Forms Are Followed By Verbs In Past Participial Forms. For Example: 1) I Am Done With The Assignment. 2) I Have Finished Cooking. I Discovered That This Rule Is Unequally Yoked With These Examples: 1) I Do Known Him. 2) I Can Sung. Pls Explain.

Hi Cijo,

That rule is not correct. In 1, although 'done' is formed from the past participle, it is an adjective in this case. In 2, 'have done' is a present perfect verb. The other two forms you mention are not correct, I'm afraid.

All the best,
Kirk

The correct rule goes like this: Auxiliary verbs in PRESENT PERFECT tense form are followed by verbs in past participle. Example: I have eaten She has seen You have known.

Can you tell me if these two sentenses correct? - Children have to greet their teachers. - All children are to gather in the school hall at once! In these sentences I compare two modal verbs have to and be to. As the book says the first one means - customary obligation, the general rule and the second one means an order. Are they grammatically and lexically correct?

Hello ifencing,

Both sentences are fine.

'Have to' can be used with both meanings, so you could use 'have to' in the second sentence as well.

Hi rosario70,

I am trying to explain to professional colleagues who are translating into Spanish the difference in the use of SHALL in the following two phrases: "Any requirement shall be permitted to be modified..." "..the stories in the building shall be determined as follows.." The former being optional, given the use of the verb permit, vs. the latter which is a mandatory requirement. I have looked at modal verb entries, but not being a professional language teacher, I just don't know how to explain how the difference in the use of "shall" when it modifies the verb permit vs when it is used alone. The colleague insists that the use of "shall" makes the modification a requirement, and ignores the verb "permitted". This issue has to do with building codes. Thank you for any help you may be able to offer.

Hello Patricia MacDougall,

In most cases, 'shall' and 'will' are interchangeable. However, when used in contracts there can be a difference. 'Will' refers simply to a future time, while 'shall' represents an obligation, requirement or duty.

The topic is discussed on this page, which I think will clarify it for you:

https://english.stackexchange.com/questions/3389/shall-and-will-in-legal-requirements

 

Peter

The LearnEnglish Team

Thank you for the reference and your quick reply, Peter. I see that in legal terms "shall" is complicated. It seems the case especially when translated. I had discovered various references to the "shall/must" argument and the link you have given me supports the ambiguity argument. Finally, with many examples in the same building code between "shall be permitted" vs "shall" I was able to convince the colleagues that the former is an optional provision, while the latter is an obligatory requirement.
Hi Patricia, I fear you may have over-analysed this. The word 'shall' in both of your examples does indeed imply a mandatory requirement. In the case of "shall be permitted", the 'shall' simply refers to the obligation that permission be granted (should it be requested). There is no ambiguity in the value of the word itself, only a difference in context. Buena suerte con los colegas.

Hi, I have a question. Would 'depending on' be considered a modal verb? As in 'I might go for a walk, depending on how the weather holds out'. Having trouble working out which grammatical category this fits into. Thanks.

Hello shani,

'Depending on' is a participle phrase, not a phrasal verb. The verb is 'depend' and it is often followed by a preposition ('depend on') but it can also be used by itself:

  • Our answer depends on the cost.
  • Are you going to buy it? It depends how much it costs.

You can see a list of common verbs which are followed by prepositions on this page.

I was to have left on Thursday. But on Thursday I had a terrible cold so I decided to wait till Saturday. In the above example, can I use "had to" in place of *was to have left"

Hello amol,

In terms of grammar, you can say 'I was to have left' or 'I had to leave', but the meaning is slightly different.

'I was to have left' means the same as 'I was supposed to leave'. It describes a plan or intention which was not completed.

'I had to leave' describes an obligation. It suggests that something made it necessary for you to leave. This may have been something you know in advance or something which surprised you.

There is a problem with the sense of the second sentence, however. 'I had to leave' suggests you had no choice, but the second part of the sentence makes it clear that you did have a choice, because a cold was enough to change your mind. This would appear to be contradictory.

Hello SonuKumar,

Both are possible.

There are many ways of talking about future time. If we are asking about a person's intention or plan then 'going to' is appropriate. If we are asking about a decision made at the moment of speaking then 'will' is more likely.

You can read about future forms on our page on the topic.

Please tell me, when I do exercises how I drag the words into the answer box if there is more than one word?

Hello Amaavee,

Moving items is done by clicking rather than dragging. Click once on the item and then click again on the box where you wish it to go. If you click on an item already in the box you will swap it for the new item; if you click on the box itself you will add the item.

Hi, I was watching a movie and I found one girl says to a boy 'I promised my mother not to do this' and then the the boy says to the girl ' why would you say this?' Here, does this sentence mean 'Why did you say this?' or 'Would' has a different meaning like in 2nd conditional sentence? I don't understand? Please explain with some further examples?

Hello jitu_jaga,

'would' can be used to speak about willingness to do something in the past – that is how I would understand this here. It's another way of saying 'Why did you want to say this?'

'would' is also used to express a hypothetical situation; perhaps one could argue that that is how the boy was thinking about it, but in this context I'd say it's more an expression of willingness.

In any case, it's clear that it means the same thing as the past simple form you suggest in this context.

Sir, I had to wash a lot of clothes. This sentence means that I did wash the clothes, but if I say " I had to wash a lot of clothes, and then add, but I couldn't or didn't". This means that I didn't wash the clothes. Now The question is, Should I use 'Had to' if I didn't wash clothes adding 'I couldn't or I didn't ' or Should I use 'Supposed to' like this - I was supposed to wash a lot of clothes, but I couldn't or I didn't ? Do they both mean the same thing or Is one of them not correct ? while the other is correct.

Hello SonuKumar,

If you say I had to wash a lot of clothes then we do not know if you washed them or not; we know only that you had this obligation. We may guess what you did, but the sentence does not tell us.

Hello! I have a question regarding some examples with modal verbs if you could help me. Examples: 1.They took some extra blankets în case they should get cold. 2.It's essential that everyone should arrive on time. 3.They were going to call this morning, so he should know about the job by now. Why can't we put, in all the sentences,'would' instead of 'should'?

Hi Carmen,

There structures in these three sentences are different. In 1, 'in case' is not followed by 'would', but rather by a past tense verb. In this case, the verb should be in the past simple, since this sentence refers to the past. I can see how 'would' would seem to make sense here, as it speaks about a hypothetical situation, but 'would' isn't used in a clause beginning with 'in case'.

In 2, 'It's essential that' begins a clause that speaks of necessity. Although 'should' is not exactly wrong here, a subjunctive form such as 'arrive' is more common. 'would' isn't used here.

In 3, 'should' indicates what we expect to communicate probability. 'would' can be used to indicate probability in some cases, but this form is a little unusual and is not usually used in one clause connected to another clause.

I hope that helps you.

All the best,
Kirk

Hi Thanks for the prompt response. As regards the use of 'would' to refer to future events by some publications, I would have sent you the snapshots/screenshots of such usages so that you could appreciate the context of the use. But posting pictures in response box is not possible on your site. I think, this is probably due to the use of 'could' and 'might' as tentative versions of 'can' and 'may' respectively that 'would' is used in the same vein as a weak version of 'will' and used for real future references. You can throw better light on it. Eager to hear from you on this topic. Regards

Hi Adya's,

The examples you provided are inconsistent in my opinion. As you mention, the problem is the use of would for real or certain future events. There needs to be an explicit or implied qualification of some kind to make the event unlikely or uncertain.

In your examples we have the opposite. We have decided introduces a decision which has been taken and is, therefore, necessarily real; will is needed here, not would. In the second example the phrase if you buy today makes it clear that a real or likely situation is in mind and so would is inconsistent.

I can't really think of a context in which would would be appropriate here, and I think it is far more likely that these are simply inaccurate sentences and that the newspapers in which they were published would benefit from better proofreaders!

Hello This question has been baffling me for some time. Even in standard newspapers I find frequent use of 'would' to refer to future events. There is no indirect speech reporting with a past tense reporting verb, yet 'would' is used to describe future events! For example, "We have decided that we would not attend the meeting". Or like, "If you buy today, we would give you a good discount". Is it correct to do so? Please respond and clarify my doubts. Regards

Hello Adya's,

Those do not look like standard sentences to me. I can't comment on their use because I don't know the source or context but I would not say that those are correct examples.

Remember that people do not always speak in fully grammatical forms. We make mistakes or change our minds in the process of expressing ourselves. This may be the issue if these are direct quotations from people.

Hello Learner Kid,

This is an example of the modal use of 'need'. A test is to try to replace the word with other modal verbs:

You need not have gone there.

You could not have gone there.

You should not have gone there.

Sir, It has to be the same, something or whatever. It should be the same, something or whatever. I think the first one says there's obligation that it has or is to be the same. The second one says It will probably be the same. it shows the probability and a reason to believe. Right ?

Hello SonuKumar,

As you know, modal verbs are very much context dependent in terms of meaning so it's not really possible to give an answer to this question without guessing what the context might be. In general, 'has to' suggests that something is necessary, required or obligatory while 'should' could suggest a preference or an expectation.
