Modal verbs

Please listen and read.

Lee: Good morning, sir. I’d be pleased to know how we use modal verbs in sentences and what they express.

Can could
May might
Must -
Shall should
Will would

Yuma: Well, please listen. We use modals with another verb. We use them to express ability, probability and possibility, permission, request, offers and invitations, suggestions, obligations, predictions and simple future.

1. Modals “can” and “could” are used to express ability (“Could” is the past tense form of “can”. It is used to talk about what someone or something was able to or allowed to do in the past.)


● I can swim like a fish.
(= I am able to swim like a fish.)

● I could swim like a fish when I was a school boy.
(= When I was a school boy I was able to swim like a fish. Now I am not able to swim like a fish.)

● My grandma can run fast.
(= My grandma has the ability to run fast.)

● My grandma could cook fast when she was young.
(= My grandma had the ability to cook fast when she was young but now she doesn’t have the ability.)

● What man can not computers can.

● Computers can help us learn faster and store information longer.

Do you understand?

Lee: Yes, sir. You have made modal verbs easy to understand.

Yuma: Thanks. Try making sentences using “can” and “could” yourself.

Lee: Yes, sir with pleasure.

● I can speak English fluently.
● I can drive a car over 400 kilometres non stop.
● My mom could climb trees when she was a teenager.
● My grandpa could assemble cars when he was in Germany.

2. “Can” and “could” are used to ask for help,too.

Yuma: Well done, Lee. You are smart for learning. Modals “can” and “could ” are used to ask somebody to help you.


● Mom, can you help me with the homework?(I have to hand in this homework today, mom.)
● Hello sir, can you help me across the street?(There’s heavy traffic.)
Can you show me the road to the supermarket?
Can you guide the students around the zoo?

“Could” is a more polite form of “can” when asking for help or permission.


● Excuse me, sir. Could you post this letter for me on your way to the office? (Of course I can.)
Could I have one more glass of juice, please? (You can have as much as you need.)
Could I park my car in front of your gate?(I’m sorry. I can’t allow it.)
Could you help me open the window, please?(With pleasure.)

Lee: Thank you so much, sir. Could you explain the difference between possibility and probability and how we express them using modals.

Yuma: With pleasure. Listen, please.

Possibility is a fact that something might happen or be true but is not certain.

Probability is how likely something is to happen, the level of possibility of something happening or being true

Lee: When do we use ‘may’, ‘might’ and ‘could’, sir?

Yuma:We use may, might and could to say that something is possible, but not certain:

May is used to express possibility.

What the minister says may or may not be true.

● Our team may well win the match.
● It’s rather a cloudy sky. It may rain soon.
● I may visit you tomorrow before I leave for New Zealand.

“Might” is used when showing that something is or was possible. (Might is the past simple form of the verb “may”).


● I gave my grandpa a mango as I thought he might like it.
● Very politely my grandpa asked me if he might have a guava instead.
● You might get to the party in time if you walk fast but I’m not so sure.

“Could” is used to express possibility, especially slight or uncertain possibility.

● Migrant workers could face long delays as many trains services have been cancelled.

Lee: How do we ask for and give permission, sir, using modals?

Yuma: We use “can”, “could” and “may” to ask for and give permission to do something.

“Could” and “may” are more formal and polite than “can”.

With parents, friends, juniors...we generally use “can'' as we don’t have to be formal.

Lee: Yes, sir. I can

May I ask a question, mam? (Yes, you may ask any question.)

Yuma: We use “can’t” and “may not” to refuse permission to do something or for something.

Could you get me a glass of water, please? I’m thirsty.
Would you type one more letter for me, please?

Can you get me a drink?
Will you wait for an hour?
