Pronunciation

  • IPA: /dʒeɪ/[1]

Etymology

It is Middle English jai, borrowed from Old French jai (Old North French gai, modern French geai),[2][3][4] from Late Latin gaius (“jay”),[2][3][5] perhaps from the Roman name Gaius, following the custom of giving birds personal names, as with robin and martin.[3][4][5] Etymonline thinks the word is probably imitative of the bird's harsh cry, influenced by the name Gaius.[2]

Earliest recorded meaning

The European jay: before 1300 in Kyng Alisaunder, according to Barnhart, and before 1310 in the OED.[3][6] It is earlier as a surname, from the late 12th century.[2]

Semantic evolution

Jolly as a jay was a Middle English expression for “very happy”.[2] A chatterer or a flashily dressed person is from the 1520s.[2] The American blue jay, a different bird, is called jay from 1709.[2][3] A rustic, a dupe, is American from 1884, and the adjective “worthless, fourth-rate”, as in a jay town, from 1888.[2] Jaywalker, from this sense of a foolish person, is American from 1917.[3]
