Cách sử dụng
The word 'roughen' means to make something rough or uneven. It is commonly used in construction and woodworking when a smooth surface needs to be made rougher for better grip or to improve adhesion. For example, one might "roughen" the surface of a wall with sandpaper before painting to create a better bond between the paint and the wall. It can also be used in describing a roughening of a person's behavior, such as when someone's tone or manner becomes harsh or unpleasant.
