Can x Could x Be able to
Hello and have a nice Sunday!
Could you help me understand the use of can/could and be able to better?
I was reading a textbook where I found out a small difference.
Thank you very much.
Re: Can x Could x Be able to
Can- present ability/ Could past ability
For possibilty, can is a stronger possibility.
The general distinction between can/could and be able to is the occasion:
I could swim when I was five / I wasn't able to swim yesterday because I was ill.
However, this distinction is far from a rule.
