Modal Verbs Should, Could, Would

Modal Verbs Should, Could, Would – How to Use Them Naturally in English (with Examples and Exercise)

Hello, dear English learners. Modal verbs are small words, but they do a lot of heavy work in English. Three of the most useful — and most confusing — are:

should, could, and would

We use them every day to:

• give advice
• make polite requests and offers
• talk about possibilities
• describe habits in the past
• and imagine different situations

They are especially important for B2 First and C1 Advanced speaking and writing, because they help you sound more polite, more natural, and more precise.

Let’s look at each one clearly and practically.

SHOULD – Advice, Expectation, and Opinion

1. Should for advice and suggestions

We use should to say what is a good idea or the right thing to do.

• You should never hitchhike on your own.

• “I feel a bit dizzy.” – “You shouldn’t go to work. You should go to the doctor.”

• What should I make for dinner?

• Should I wear a white shirt or a blue one?

Meaning: “This is a good idea” / “This is the right thing to do”.

2. Should for expectation

We also use should when we expect something to be true or to happen.

• The train should arrive in about ten minutes.

• The doctors should encourage their patients to exercise more.

• This new law should solve many problems.

Meaning: “I expect this to happen / I think this is probably true.”

3. Should to show strong agreement

In spoken English, should is often used to agree strongly.

• “Look at those clouds. It’s going to rain.” – “I should think so too.”

• “This will make the house much quieter.” – “I should hope so!”

Teacher’s tip

Should is softer and more polite than must.

Compare:

• You must see a doctor. (strong, almost an order)

• You should see a doctor. (advice)

COULD – Past Ability, Polite Requests, and Suggestions

1. Could for past ability

Could is the past form of can when we talk about general ability.

• I could swim when I was five.

• It was very quiet, so we could hear everything.

• They searched for half an hour but couldn’t find the keys.

2. Could for polite requests

We often use could to sound more polite and less direct.

• Could you turn down the TV, please?

• Could I borrow your car tonight?

• Do you think you could look after our cat?

Could is more polite than can.

3. Could for suggestions

We also use could to suggest ideas.

• You could do the washing-up and I could vacuum the floor.

• You could move the desk next to the window.

• We could go for a walk after dinner.

Meaning: “This is one possible idea.”

WOULD – Politeness, Imagined Situations, and Past Habits

1. Would for polite offers and invitations

Would is extremely common in polite English.

• Would you like a cup of tea?

• Would you like to have a drink after work?

2. Would for imagined or unreal situations

We use would in conditional sentences to talk about hypothetical situations.

• What would you do if you had more free time?

• If I didn’t work as a teacher, I would be a writer.

• Don’t open the window — it would be very cold.

3. Would for repeated past actions

We can use would to talk about past habits (similar to used to).

• When we were children, our mother would make pancakes every Sunday.

• When I was a student, I would stay up all night before exams.

4. Would like / would love / would hate

We use would to talk about preferences politely.

• I would like to learn another language.

• My parents would love to go on a second honeymoon.

• I would hate to live in a very noisy city.

Common Mistake

Don’t confuse:

• could (possibility/suggestion/past ability)
• would (imagined result/politeness/habits)

Examples:

• We could go to Italy. (it’s an idea)

• We would go to Italy if we had more money. (imaginary situation)

Summary

• Should → advice, expectation, opinion
• Could → past ability, polite requests, suggestions, possibility
• Would → politeness, imaginary situations, past habits, preferences
