凹 (āo): เว้า

There is a concave dent in the middle of this wooden board, as if it had been struck hard by something.

He fell off his motorcycle, and the front of his helmet got a dent, but fortunately he wasn't hurt.

This mountain road has been in disrepair for years; its surface is full of pits and hollows, and driving over it is very bumpy.

The craftsman carved patterns into the wooden board with a engraving knife, then applied gold powder, making it look especially exquisite.
