When we talk about permission, we generally use these three modal verbs:
In general, can is used to talk about what someone is or isn’t allowed to do. Could is used when speaking about the past.
Here are some examples of how to use modals of permission.
|The boss said we can wear princess dresses to work tomorrow.
||The boss said we could wear princess dresses to work last week.
|You can play loud music until 10pm.
||Last year you could play loud music but the neighbors complained to the police, and now loud music is forbidden.
|He can borrow my running shoes if his break.
||I told him he could borrow my running shoes.
Remember that the negative of can is can’t or cannot, and the negative of could is couldn’t or could not.
|You can bring your dog to the hotel.
||You can’t bring your dog to the hotel.
