Modal verbs are a part of the larger category called auxiliary verbs which are verbs that cannot be used on their own. They need to be accompanied by another (main) verb. Sometimes modal verbs are called modal auxiliaries. The following words are modal verbs: Can, Could, May, Might, Must, Shall, Should, Will, Would. They are modal auxiliary verbs that provide additional information about the verb that follows it. Modal verbs are used to express ability, obligation, permission, assumptions, probability and possibility, requests and offers, and advice. Each modal verb can have more than meaning which depends on the context of that sentence (or question).  

You can go now. (= permission) I can play the guitar. (= ability)

Structure with Modal Verbs A Modal verb is followed by another verb in the base form (the infinitive without the 'To') and they are not conjugated (we don't add an 'S' in third person). See the following structure: Subject + Modal Verb + Verb (base form of the infinitive)   

I can speak English (NOT: I can to speak English) He can speak Spanish (NOT: He can speaks Spanish) She can speak Spanish (NOT: She cans speak Spanish)

Modal Verbs in Negative Sentences Subject + Modal Verb + not + Verb (base form of the infinitive)   

You must not walk on the grass. (= You mustn't walk on the grass.) He cannot speak Arabic. (= He can't speak Arabic.) We should not be late. (= We shouldn't be late.)

As you can see in the examples above, contractions of the Modal verb + not are normally possible. The negative of can is cannot ('not' is joined to 'can') and the contraction is can't Modal Verbs in Questions Modal Verb + Subject + Verb (base form of the infinitive)

  

May I help you? Can I have another piece of cake please? Would you like to come with us?

Should Summary Chart Next activity See our notes about other Modal Verbs. Shall English Grammar - Modal Verbs

SHALL Shall is not used very much nowadays and mostly in formal speech and some legal documents. Originally Shall was used instead of Will in first person (with I and We) when talking about the future. Now almost everyone uses Will with all subjects. Nowadays, the most common use of shall in everyday English (although not in American English) is in questions that serve as offers or suggestions: "Shall I ...?" or "Shall we ...?" Situations where Shall is still occasionally used: 1. Suggestion

Notice how each of these can easily be replaced by should.    

Shall I get a pizza for dinner tonight? Shall we take a taxi home? It's cold. Shall I close the window? Shall we go now?

2. Offers / Volunteering to do something   

That bag looks heavy. Shall I carry it for you? Shall I wait for you? I shall make the arrangements for you.

3. Instructions (asking for or giving)   

What shall I do with your mail when it arrives? I shall meet you there at 7. You shall not pass! (said Gandalf to the Balrog in Lord of the Rings)

4. Promises  

You shall be the first person to know. (= I promise that you will be the first person) I shall get you a new bike for your birthday.

5. Confirmation (Statement of Fact) Notice how each of these can easily be replaced by will.   

I shall turn 30 next week. We shall know the results of the exam next week. I shall meet you there at 7.

6. Formal written regulations and rules This is very formal and normally avoided in spoken English. The passive is most often used in this situation.  

A record shall be kept of all students arriving late to class (= school regulations) Members of the board of directors shall be elected annually (= company regulations)

The Negative of Shall The negative of shall is shall not (= will not). The contraction of shall not is shan't (= won't). It is very rare to hear this used nowadays though you may find it written in older texts. 

I shan't let the children bother you.

Shall in Question Tags Shall is used in questions tags when the main verb is Let's. 

Let's go to the beach, shall we?

English Grammar Notes

We normally use WILL to speak about the future. It is always combined with another verb. Since WILL is classified as a modal verb (like can, would, could, should) it has the same characteristics: 1. It does not change in the third person (i.e. he, she, it) 2. It is always combined with another verb in the base form (i.e. without 'to') 3. We don't use it with 'Do' in questions or negatives. Examples of Will:    

I will go to the cinema tonight. He will play tennis tomorrow. She will be happy with her exam results. They will take the bus to the South next week.

When to use WILL We use WILL in the following circumstances: 1. For things that we decide to do now. (Rapid Decisions) This is when you make a decision at that moment, in a spontaneous way.   

I'll call a taxi for you. I think we'll go right now. (I just decided this right now) Which one? Um, I will have the chicken sandwich please.

2. When we think or believe something about the future. (Prediction) This can be based on personal judgement or opinion.   

The President will not be re-elected at the next election. I think it will rain later so take an umbrella with you. I think you will find the movie interesting.

Notice how you often use "I think..." before the subject + will. 3. To make an offer, a promise or a threat.      

You look tired. I'll finish the dishes for you. I will do my best to help you. If you say anything I will kill you! I will have it ready by tomorrow. I'll drive you to work if you want. Don't worry, I won't tell anyone. (won't = will not)

4. For a habit that is a predictable behaviour  

My daughter will fall asleep as soon as she is put into bed. He will give up if he starts losing. He always does that.

5. You use WON'T when someone refuses to do something.  

I told him to clean his room but he won't do it. She won't listen to anything I say.

Negative Sentences with WILL In the negative, we add NOT to the end of WILL and not to the main verb. (= will not) Examples: 

I will not be in the office tomorrow. (correct)



They will not stay here. (correct)

I will be not in the office tomorrow. (Incorrect) They will stay not here. (Incorrect)

Contractions It is possible to use contractions in both positive and negative sentences. With positive contractions WILL becomes 'LL and is joined to the subject: Positive Contraction I will

I'll

You will He will She will It will We will You will They will

you'll he'll she'll it'll we'll you'll they'll

With negative contractions, will not becomes won't: Negative Contraction I will not You will not He will not She will not It will not

Modal Verbs The modal verbs are: can

could

may

might

shall should will

would

must We use modal verbs to show if we believe something is certain, probable or possible (or not). We also use modals to do things like talking about ability, asking permission making requests and offers, and so on. Modal verbs This lesson has two parts. Part 1 explains the grammar of modal verbs and where they are placed in a sentence or question. Part 2 explains the meaning of each modal verb and provides example sentences.

Modal verbs are also called modal auxiliary verbs, modal auxiliaries, or simply modals. These verbs are a subcategory of auxiliary verbs , which means they cannot Read lesson * en español be used without a main verb. English has ten modal verbs.

While the meaning and usage of modal verbs is complicated, the grammar is simple. Modal verbs are not conjugated: they have no tense and no person, so they never change. All modal verbs must be followed by a main verb in the base form except for ought which is followed by an infinitive. subject modal main verb verb (base form) They

To learn more details about modal verbs and how they express moods such as ability, possibility, necessity or other conditions, go to page 2 . Modal verbs (part 2) This lesson is in two parts. Part 1 explains the grammar of modal verbs and where they are placed in a sentence or question. Part 2 explains the meaning of each modal verb and provides example sentences.

One reason modal verbs are difficult for students to master is that their meanings change depending on the context. Sometimes, two, three, or even four modal verbs can mean the same thing. This page defines each modal verb and provides example sentences to give an idea of what they mean in context. Be aware that only a few examples for each modal verb can be given here. While usage and differences can often be subtle, this lesson will provide a general idea of how and when to use modal verbs.

Remember, English has ten modal verbs. can

could

may

might

shall

will

would

The modal verb can is indicates ability or possibility. Birds can sing. We can speak English. I can take you to the train station. Ideas can change. In questions, the modal can is used to request permission to do something or to ask about possibilities.

Yes / No questions

Can I help you? Can Tom eat dinner with us?

Wh – questions

Who can answer the question? When can we have the results?

The modal could is used to indicate possibility now. I could eat three pizzas. (I am very hungry) This could be my big chance. (this is an excellent opportunity) The modal could + have is used to indicate an unrealized possibility in the past. These examples resemble the conditional (explained below) because there is an implied “if” clause. implied if clause

I could have told you that.

(if you had asked me)

It could have been a disaster.

(if they had lost control)

The rain could have ruined the party. (if we had been outdoors) Note that can indicates an ability in the present while could indicates an ability in the past. present I can speak French. (I know how to speak French at this moment.)

past

I could speak French when I was young. (In the past, I spoke French. Now, I am unable to speak it.)

The modal verb could is used to speculate about future possibilities. In the following examples could and might are synonomous. It could / might rain tonight. This could / might be dangerous. In Yes / No questions, could is used to speculate about present of future possibilities. Could she be the assasin? Could this be a mistake? Could you return tomorrow? Could and can indicate a range of options (hypothetical possibilities). We could / can go see a movie, or we could / can stay home. I could / can become a doctor, or I could / can become an artist. The modal could is also used to make requests. In these examples could and can are synonymous but could is more polite. Could / Can you open the window? Could / Can you help me move this sofa? The modal verb could is very important in the formation of conditional sentences. Note there are two clauses: one clause contains the modal could and the other is the result clause. In these situations, could is used to express hypothetical results.

If we leave sooner, we could take the train. I could pass the test if I study more. Could is also used to make conjectures about past hypothetical results. The results were not realized because a particular condition was not met. If we had left sooner, we could have taken the train. I could have passed the exam, if I had studied more. I’m glad we took umbrellas. We could have gotten soaked. The modals will and shall are used to talk about the future. These modals indicate an intention or an action that is expected to happen in the near or distant future. When used in this type of phrase, there is no difference in meaning between these two modals; however, shall is rarely used in American English. I will / shall close the door for you. Tom will / shall meet us at the train station. They will / shall graduate in two years. In wh- questions, will and shall are used to ask about future possibilities. Who will / shall drive the car? What time will / shall we meet? When will / shall I see you again? In yes-no questions, will is used to ask a favor and shall is used to offer a favor. Note that the modal verb will is used with the second person (singular and plural) while shall is used with the first person (singular and plural). singular 1st pers.

Will / Shall I close the door for you?

2nd pers. Will / Shall you close the door for me?

plural Will / Shall we close the door for you? Will / Shall you close the door for us?

Will is also used to ask for information about a likely possibility regarding somebody or something. Will you stay in a hotel? Will good triumph over evil? Shall is used to ask about a preference. In these examples, shall and should are synonymous. However, in American English, shall is rarely used. Remember, in questions shall is only used in the first person singular and plural.

singular

plural

1st pers. Should / Shall I stay here?

Should / Shall we stay here?

2nd pers.

Should / Shallyou call him?

3rd pers. Should / Shallhe return later?

Should / Shallyou call him?

Should / Shall they return later?

The modals may and might are used to indicate an uncertain future action. These two modals are synonymous. I may / might go to the park, or I may / might stay home. This may / might be a bad idea. It may / might rain tonight. The modal verbs may or can are used to give instructions or permission. May is more polite. You may / can now board the airplane. They may / can begin the exam in one minute. The modals may, can, and could are all used in Yes-No questions to make requests. May and could are more polite than can. May / Can / Could I see your passport? May / Can / Could we have some more water, please? Sometimes the modal verb might is used in place of may, can, or could, but this is rare in American English. May / Can / Could / Might I be of some assistance? May / Can / Could / Might we offer you a suggestion? The modal must is used to indicate a recommendation or an obligation. You must see this movie. Tom must see a doctor immediately. Must is also used to indicate an assumption. My watch must be broken. Tom must have left. He is not here.

In Wh– questions, must is used to indicate an obligation and can be replaced with the modal should. In American English, should is much more common in this context. more common

less common

When should we be there? = When must we be there? Who should I talk to?

Who must I talk to?

The modal verb must is sometimes used to form rhetorical questions, especially when you want a person to stop doing something. Must you make so much noise?

Please be quiet. =

Must he be so cruel?

I wish he were kinder.

The modals should and ought are used to indicate an obligation. In this context, these two modals are synonymous. Remember, ought is the only modal verb followed by an infinitive. You should call your mother.

You ought to call your mother.

I should go home now.

I ought to go home now.

In questions, the modal should is used to ask if an obligation exists. Ought is never used in questions in American English.

Yes / No questions Should he call her? Should we pay now?

Wh– questions

When should we leave? What should I wear?

The modal verb would, followed by like, is a polite way of stating a preference. We would like a table for two. I would like a glass of white wine. In questions, would + subject + like is a polite request for you to make a choice. Where would you like to sit? Would you like to start with a salad? The modal would can make a request sound more polite.

less polite

more polite

Come here, please.

Would you come here, please?

Stop making that noise.

Would you stop making that noise?

Would is used to explain a possibility which is a result of a hypothetical or real condition. She would be surprised if you came to the party. I would go with you if I didn’t have to work. I would have arrived sooner if I had not lost my keys. The modal verb would is used to introduce habitual actions in the past. When I was a student, I would swim every day. When Tom lived in France, he would write me letters in French. English The Easy Way Modal Verbs 1. Home 2. English Grammar 3. English Verbs 4.

Modal Verbs

Everyone can understand modal verbs! What are model verbs? Model verbs are also called auxiliary verbs, helping verbs and model auxiliaries. Model verbs are not complete verbs, and they can only be used with a verb. The usage of model verbs: Model verbs stay in the base form - bare infinitive - the bare infinitive is the infinitive without "to" before the verb. The following model verbs are used to with the present tense: can, will, shall, ought to, must, need, may The following model verbs are used in the past tense: would, should, could, might

Model verbs are used to answer questions in the short form   

yes, I do. yes, we can. No, I don't.

Model verbs can be used as part of the grammar structure of the sentence, such as when used with the perfect tenses. When are model verbs used: Prediction - Will and Shall Will and shall can be used to state predict that an event or an action will take place or will occur The model verbs can used to make a prediction about an event or action about the future.  

I think we will be able to go and see the move tonight. My mother thinks we will not get home be it starts to rain.

Requests - Offers - Suggestions - Can - Could - May - Shall To make requests, offers or suggestions can be stated with the model verbs Permission - Can - Could - May - Might Can, could, may and might are model verbs that can be used to give permission or deny permission to do something or to someone. Can I help you cook dinner? You may not watch T. V. after dinner. Certainty - Possibility - Can - Might - may- Could - Shall -Can, might - and could are model verbs that can be used to state certainty and possibility. Do you think it might rain tomorrow night? I might be home before midnight. You can come over tonight if you would like to. Ability - Inability - Can - Could - Able to My father hopes that we will be able to go to the moves. I can not go to Europe with you. Verbs: Be, Auxiliaries, and Modals The Eight Forms of Be The verb be has eight forms, with am and are as present tense forms along with is, and both was and were as past tense forms. Base be

Present Tense Forms -ing am, are, is being

Past was, were

Past Participle been

An independent clause needs a complete verb. Verb forms such as the -ing form and the past participle are not complete because they do not show tense. They need auxiliary verbs to complete their meaning as a verb of a clause. A complete verb includes a verb form preceded by any necessary auxiliary verb or modal auxiliary verb. Auxiliary Verbs

do: does, do, did be: be, am, is, are, was, were, being, been have: has, have, had Modal Auxiliary Verbs will, would can, could shall, should may, might, must Auxiliary verbs and modal auxiliary verbs can be used in combination. Whatever the combination, the verb form immediately following the final auxiliary or modal verb is fixed: base form, -ing, or past participle. Try the following tips to decide which form to use. Combining Auxiliary, Modal Auxiliary and Verb Forms 1. After do, does, did, will, would, can, could, shall, should, may, might, and must, use the base form. He might stay. They must have dinner soon.

Did she leave? 2. After has, have, and had, use the past participle. It has snowed. They should have gone (not "They should have went"). They had eaten when I arrived. In informal speech, we run sounds together, and the pronunciation may be mistakenly carried over into writing. She should have left that job last year. The pronunciation of the contraction should've is probably responsible for the nonstandard form should of. Edit carefully for the appearance of the word of in place of have in verb phrases. 3. After be, am, is, are, was, were, and been, use the -ing form for active voice verbs. She is taking her driving test. You were watching. He might have been driving. They could be jogging. To form a complete verb, always use a be auxiliary before the -ing form. The -ing form alone can never be a complete verb in a clause. 4. After be, am, is are, was, were, been, and being, use the past participle for passive voice. They were taken to a tropical island for their anniversary. The faucet should be fixed.

The cake might have been eaten. The house is being decorated. Note: Be requires a modal before it to form a complete verb (could be jogging; will be closed). Been requires have, has, or had (have been driving; has been eaten). Being must be preceded by am, is, are, was, or were to form a complete verb.

They have no to-infinitive form, -ing form, past form or -ed form. We have to reword what we want to say by using other expressions:

I’d love to be able to see the Taj Mahal one day. Not: I’d love to can see the Taj Mahal one day.

They had to sell their house. Not: They musted sell their house. Affirmative (+) forms Modal verbs are placed first in the verb phrase (after the subject) and are followed by a verb in the base form. The next verb may be a main verb or an auxiliary verb ( be, have): Modal verbs do not change form for tense or person. Modal verbs can be followed by the substitute verb do: A:

We thought he might sell the house B:

Yes, he could do. Modal verbs cannot be used with another modal verb:

Windsurfing can be difficult. Not: Windsurfing can might be difficult. or Windsurfing might can be difficult. Modal verbs always go before other verbs in a verb phrase: [in a restaurant after a meal]

I think the bill could be expensive. Not: I think the bill could expensive.

You can go swimming, go for a long walk or visit the exhibition.

Not: You can swimming, go for a long walk or visit the exhibition. Modal verbs can only be used alone when the main verb is clearly understood: A:

She could take the bus. B:

Yeah, that’s true. She could. (She could take the bus.) A:

He may be wrong, you know. B:

Yes, he may. (Yes, he may be wrong.) Negative (−) forms Warning: Negatives are formed by adding ‘not’ after the modal verbs. We don’t use don’t/doesn’t/didn’t with modal verbs:

We can’t hear very well at the back. Not: We don’t can hear very well … Question (?) forms Warning: The subject and the modal verb change position to form questions. We don’t use do/does/did:

Could you help me? Not: Do you could help me?

Will it be a problem? Not: Does it will be a problem?

Why can’t you come too? Not: Why don’t you can come too? We use modal verbs in question tags:

You can’t live like that, can you? It could be any of those things, couldn’t it? See also:  Question tags  Tags Contracted forms In speaking shall and will are often contracted to ’ll and would is contracted to ’d, especially when they follow a pronoun:

I’ll see you later. We’ll never get there.

I knew they’d love it. The negative forms of modal verbs are often contracted. modal verb

Loud noises may sometimes frighten dogs and other animals. You’ll probably notice something different about the house. When the main verb is understood, we can put the adverb between the subject and the modal verb: A:

I can never remember Flo’s number. B:

I never can either. (I can never remember Flo’s number either.) Dare, need, ought to and used to (semi-modal verbs) Dare, need, ought to and used to are often called semi-modal because in some ways they are formed like modal verbs and in some ways they are like other main verbs.

Like modal verbs, ought to and used to do not change form for person. Needn’t and daren’t do not have a third person -s in the present:

It used to be so easy. It ought to be easy now. She needn’t worry. John daren’t tell Ruth about the accident. Like main verbs, the negative form of need, dare and used to is made by using do. But it can also be made without using do (like modal verbs). Compare

You don’t need to dress smartly.

You needn’t dress smartly.

We don’t dare (to) tell him.

We daren’t tell him.

The negative form of ought to is not made with do:

We oughtn’t to spend so much money. Not: We don’t ought to spend so much money. Like main verbs, the question form for need, dare and used to is made by using do:

Does she need to get a camera before she goes away? Did you use to play football when you were a child? Question and negative forms of ought to are rare. See also:    
