Д To
ask
PERMISSION to do something we use
can
or
could:
•
I
take another biscuit?
We use
could
to be particularly polite. If we want to put extra pressure on someone to give a
positive answer we can use
can't or couldn't.
For example, you might use
couldn't
where you
expect that the answer is likely to be 'no', or where permission has been refused before:
•
Can't/Couldn't
we stay just a little bit longer? Please?
To
give
and
refuse
permission we use
can
and
can't:
• Okay. You
can
stay in the spare room. • No, you
can't
have another chocolate.
Notice that we prefer
can/can't
rather than
could/couldn't
to give or refuse permission:
• • I'm sorry,
you
can't
borrow the car
(rather than
...no, you couldn't...)
In rather formal English,
may (not)
can also be used to ask, give or refuse permission, and
