Cách sử dụng
The word 'residual' refers to something that is left over or remaining after some things have been taken away or used up. For example, if you put a pan of water on the stove to boil, the residual heat left in the pan after you turn off the stove could still be enough to cook something else. Another example could be that after you pay all your bills, the residual balance in your bank account is what you have left to spend. In general, 'residual' is used to describe something that remains after most of it has been used or taken away. It's a way to talk about what's left over.
