Cách sử dụng
The expression "break in" usually means to enter a building or a room without permission, using force or illegally. However, it can also mean to prepare something new for use by using it a few times first. For example, you might hear someone say "I need to break in my new shoes before wearing them to work." It's important to understand the context of the situation to know which meaning is intended. It is generally not appropriate to break into a building or room without permission, as it is illegal and can be dangerous.
