Etymology

It is inherited from Middle English privat, borrowed from Latin prīvātus (“set apart from public life, belonging to oneself”),[2][3][4] originally the past participle of prīvāre (“to deprive, release”),[2][3][5] from prīvus (“one's own, single, individual”).[2][3][4] Etymonline traces prīvus to Proto-Italic *prei-wo- (“separate, individual”) and Proto-Indo-European *per- (“forward”), with a shift from “being in front” to “being separate”.[3] It is related to deprive, privilege, privation and privy.[6][7]

Earliest recorded meaning

Withdrawn or set apart from the public body, applied by Wycliffe to the religious orders: about 1380,[8][7] or probably 1384.[2] Etymonline gives “belonging to oneself, not shared” from the late 14th century.[3]

Semantic evolution

Etymonline notes that Old English had syndrig in this sense.[3] Of persons, “not holding public office”, it is from the early 15th century,[3][8] and of a place, “not open to the public”, from the 15th century.[7] Of communications, “secret, confidential”, it is from the 1550s,[3] and in private from the 1580s.[3] A private soldier, one without rank, is from 1579,[8] and the noun private in this military sense from 1781.[3] Earlier the noun meant a private citizen, from the 1590s.[3] A private school, run by individuals for profit, is from the 1650s,[3] private parts from 1785,[3] and private detective from 1868.[8]
