Cách sử dụng
The expression "well used" means that something has been used a lot, but in a good way. For example, if you have a car that you've been driving for many years and it still works really well, you could say that it's a "well-used car". Similarly, if you have a kitchen knife that you use all the time and it's still sharp, you could say that it's a "well-used knife". It's a positive way to talk about something that has been used a lot but hasn't worn out or become useless.
