Etymology

It developed from two Middle English forms:[2][3] inherited from Middle English jaiole, jaile,[2][4] borrowed from Old French jaiole (“a cage; a prison”),[4][2] and gaiol, gaole, from Old North French and Anglo-French gaiole, gaole, the form usual in Middle English manuscripts and familiar to Norman scribes.[4][2][3] Both are from Medieval Latin gabiola, Vulgar Latin *gaviola,[4][2][5] from Late Latin caveola, a diminutive of Latin cavea (“cage, enclosure, coop; a hollow, cavity”),[4][2][6] from cavus “hollow”.[7] It is related to cage and cave.[7][2]

Earliest recorded meaning

A jail, prison, and a birdcage: about 1275 in the OED,[8] about 1300 in Etymonline, and about 1200 in surnames;[4] gaiol probably before 1300 and jaiole before 1325, in Cursor Mundi, according to Barnhart.[2]

Semantic evolution

The spelling jail is first recorded in Milton's Samson Agonistes (1674), and gaol, also found in Middle English and in old law books, was recorded again from 1689.[2] Whatever the spelling, it is now pronounced “jail”; the OED says the persistence of gaol in Britain is chiefly due to statutory and official tradition.[4] In the United States a jail is usually a place of confinement for petty offenders.[4] In jail, to jail without an article is from 1447,[8] and figurative uses from about 1400.[8] The verb, “to put in jail”, is from 1604 in Barnhart and Merriam-Webster,[2][9] about 1600 in Etymonline,[4] and 1622 in the OED.[8]
