Etymology

Origin of bay¹

First recorded in 1350–1400; Middle English bai, baye, from Middle French baie, from Medieval Latin, Late Latin bāia; further origin uncertain; perhaps by back formation from Latin Bāiae, name of a spa on the Bay of Naples; perhaps of Iberian or Celtic origin

Origin of bay²

First recorded in 1275–1325; Middle English, from Middle French baée “an opening in a wall,” noun use of feminine past participle of baer “to stand open, gape,” from unattested Vulgar Latin batāre “to yawn, gape”

Origin of bay³

First recorded in 1250–1300; Middle English, shortening of abai, abay, from Anglo-French, dialectal Old French abai “barking,” derivative of abaier “to bark,” of imitative origin

Origin of bay⁴

First recorded in 1350–1400; Middle English bai(e), Old English beg- (in begbēam “a tree that bears berries”), conflated with Middle French baie, from Latin bāca, bacca “berry”

Origin of bay⁵

First recorded in 1300–50; Middle English, from Middle French bai, from Latin badius “bay, chestnut, chestnut brown”; akin only to Old Irish buide “yellow”

Explanation

A bay is an inlet along the shoreline of a body of water. A bay window occupies a similar inlet in a room. When you keep someone "at bay" you hold them off. The different meanings of bay come from different origins. For example, the idea of the word as a cove comes from the Latin bāia, while the idea of an opening is a wall is from the Latin batāre, meaning "gape." The word that means a dog's howl, however, comes from the Latin baubari, which means "to bark." Other meanings of this versatile word include a horse with reddish coloring, and a tree with leaves used to add flavor in cooking. There's nothing quite like riding a bay along the scenic bay while listening to the hounds bay!
