A "bay" is a body of water partially surrounded by land and connected to a larger body of water, such as an ocean or a sea. It can also refer to a portion of a building, such as a recess in a wall or a section of a room. Additionally, it can refer to an area designated for a specific purpose, such as a parking bay or a bay in a stable where horses are kept.

Example

1. We anchored our boat in the bay to enjoy a picnic on the beach.
2. The library has a quiet reading bay for students to study in.
3. The bus pulled over to the side of the road and let passengers off at the rest bay.
