How it's used

Often used to describe physical surfaces that are not flat, such as a road with potholes or a dented metal object. When used as an adjective, it is common to reduplicate the characters as 凹凹凸凸 to emphasize the irregularity of the surface. It functions as a descriptive term for texture rather than just a geometric concept.

Examples

This road is uneven and bumpy, it is hard to walk on.
