What does jay mean?
A jay is a medium-sized bird in the crow family, recognizable in many species by a crest, sturdy bill, and bold coloring. The best-known example is the blue jay of North America, whose vivid blue back is not a solid blue pigment but the result of light scattering through the structure of its feathers. Jays are adaptable, intelligent birds noted for their varied calls, conspicuous behavior, and ability to store and recover food. In informal North American English, a jay can also mean a foolish or irritating man, though this use may sound old-fashioned or mildly insulting. The word therefore links a familiar woodland bird with a dismissive label for someone regarded as thoughtless or nuisance. The bird sense is the more established and dominant meaning in modern reference works.
Any of various crested birds in the crow family, especially the blue jay.
"A pair of jays nested in the old oak tree."
The unqualified word is especially common for the blue jay in North American usage.
Informally, a foolish or irritating man.
"Come on, jay, let us try the puzzle again."
Informal, chiefly North American, and mildly disparaging.
The standard plural is used for both birds and, in the informal sense, men.
"Several jays gathered around the feeder."
The blue jay is not blue at all: its feathers are mostly black, white, brown, and gray, with blue borrowed from the way its feathers catch the light.

Where does jay come from?
The word comes through Middle English from Old French geai, which in turn derives from Latin gaius, the name of a jay-like bird. The ultimate origin of the Latin word is uncertain, and proposals connecting it with words for birds or colors remain debated. The English spelling was later adapted to the sound /dʒeɪ/, while the French form geai and the Latin gaius remain related forms.
