bumpy is an adjective which describes something that has a lot of bumps or lumps. An object can be physically bumpy if it has imperfections that make it uneven or rough to the touch. It can also be used figuratively to describe an experience or even a journey. For example, someone might say that the path was a bumpy road.
1. I touched the bumpy wall as I walked past.
2. We had a bumpy flight due to heavy turbulence.
3. The bumpy terrain made it difficult for us to find our way.
when used to describe a road or journey, 'bumpy' is often used as a metaphor for a difficult situation or experience. It is also used to characterize a physical surface as having bumps or lumps. In the case of the latter, it can be used to describe anything from a wall to a piece of fabric.
