Can, Could, Be able to

 

Can and could are modal auxiliary verbs. Be able to uses the verb "to

be" as a main verb. It is not an auxiliary verb, but we look at it here

for convenience.

 

Can

 

Can is an auxiliary verb, a modal auxiliary verb. We use "can" to:

 

talk about possibility and ability

 

make requests

 

ask for or give permission

 

Structure of Can

 

subject + can + main verb

 

The main verb is always the bare infinitive (infinitive without "to").

 

  subject auxiliary verb main verb  

 

+ I can play tennis.

 

- He cannot play tennis.

 

 

 

can't

 

 

 

? Can you play tennis?

 

Notice that:

 

Can is invariable. There is only one form of can.

 

The main verb is always the bare infinitive.

 

Use of Can

 

can: Possibility and Ability

 

We use can to talk about what is possible, what we are able or free to

do:

 

She can drive a car.

 

John can speak Spanish.

 

I cannot hear you. (I can't hear you.)

 

Can you hear me?

 

Normally, we use can for the present. But it is possible to use can when

we make present decisions about future ability.

 

Can you help me with my homework? (present)

 

Sorry. I'm busy today. But I can help you tomorrow. (future)

 

can: Requests and Orders

 

We often use can in a question to ask somebody to do something. This is

not a real question - we do not really want to know if the person is

able to do something, we want them to do it! The use of can in this way

is informal (mainly between friends and family):

 

Can you make a cup of coffee, please.

 

Can you put the TV on.

 

Can you come here a minute.

 

Can you be quiet!

 

can: Permission

 

We sometimes use can to ask or give permission for something:

 

Can I smoke in this room?

 

You can't smoke here, but you can smoke in the garden.

 

(Note that we also use could, may, might for permission. The use of can

for permission is informal.)

 

Could

 

Could is an auxiliary verb, a modal auxiliary verb. We use "could" to:

 

talk about past possibility or ability

 

make requests

 

Structure of Could

 

subject + could + main verb

 

The main verb is always the bare infinitive (infinitive without "to").

 

  subject auxiliary verb main verb  

 

+ My grandmother could speak Japanese.

 

- She could not speak Chinese.

 

 

 

couldn't

 

 

 

? Could your grandmother speak Japanese?

 

Notice that:

 

Could is invariable. There is only one form of could.

 

The main verb is always the bare infinitive.

 

Use of Could

 

could: Past Possibility or Ability

 

We use could to talk about what was possible in the past, what we were

able or free to do:

 

I could swim when I was 5 years old.

 

My grandmother could speak seven languages.

 

When we arrived home, we could not open the door. (...couldn't open the

door.)

 

Could you understand what he was saying?

 

We use could (positive) and couldn't (negative) for general ability in

the past. But when we talk about one special occasion in the past, we

use be able (positive) and couldn't (negative). Look at these examples:

 

  Past

 

General Specific Occasion

 

+ My grandmother could speak Spanish. A man fell into the river
