 GOOD MORNING! HOW ARE YOU DEALING WITH THIS QUARANTINE?I HOPE YOU ARE SAFE AT HOME.

LET'S START PRACTICING MODALS:


Can, Could

Ability

We use can/could to describe ability, and we use can’t/couldn’t to describe absence of ability.

Possibility

We also use can to talk about possibility.

Permission

We use can/could to talk about something that is or was allowed and we use can’t/couldn’t to talk about something that is not allowed.

Requests

We us can/could in requests, i.e. when we ask somebody to do something.

Be able to

Be able to is often similar to can and we may use it instead of can to talk about ability. But be able to is more formal and is not as common.

can/could vs be able to

We can use can and be able to to talk about general ability in the present.

She can speak five languages.
She’s able to speak five languages.
We can use could and be able to to talk about general ability in the past.

My son could walk when he was 11 months old.
My son was able to walk when he was 11 months old.

But if we want to say that someone did something in a specific situation, we must use was/were able to, or managed to + infinitive.

There was a fire in the office but all the workers were able to/managed to escape. (NOT could escape)
He lost his maps but after driving around for a long time, he was able to/managed to find the place. (NOT could find)
In negative sentences, both could and be able to can be used to say that we were not capable of doing something on a specific occasion.

It was very dark and they couldn’t find the exit. (Or They weren’t able to find the exit.)
