What does bay mean?
A bay is a broad indentation of the coastline where the sea reaches inland, typically offering calmer waters than the open ocean and often serving as a natural harbor for ports and settlements. The word extends beyond geography: in architecture it denotes an open recess or division of space, as in a bay window or a parking bay; among horse breeders it names a rich reddish-brown coat color; and in cooking, the bay tree supplies aromatic leaves used to season soups and stews. Perhaps most famously, the phrase 'at bay' describes a cornered animal or person forced to turn and resist pursuit, giving rise to the everyday expression 'to keep something at bay.' This range makes 'bay' a compact but versatile word spanning geography, building, sport, and idiom.
A broad inlet of the sea where the land curves inward.
"Ships anchored in the bay waited out the storm."
A recess, compartment, or division of space, especially one marked off by pillars or walls.
"She parked the van in the first empty bay of the garage."
Common in British usage for parking spaces ('parking bay') and in architecture for a bay window.
A horse having a reddish-brown body with black mane, tail, and points; also this coat color itself.
"The stable held two greys and a spirited bay."
A laurel tree, or its aromatic leaf used in cooking.
"Add a bay leaf to the stew and remove it before serving."
Standard plural; applies to the geographic and architectural senses.
"The coastline is dotted with small bays and rocky coves."
'At bay' originally described a hunted animal turning to face its pursuers — so keeping trouble at bay literally means making it stand its ground rather than retreat.

Etymology of bay
English actually contains several distinct words spelled 'bay.' The coastal noun comes through Old French from Late Latin 'baia,' which also yields Spanish 'bahía' and French 'baie.' The horse-color sense derives from Old French 'bai,' from Latin 'badius' meaning chestnut-colored. The barking verb goes back to Old English 'bǣgan,' and the laurel sense to the bay tree itself. Their convergence under one spelling is coincidental.
