Etymology

It is inherited from Middle English propre,[2][3] borrowed from Old French propre (“own, particular; exact, fitting”) and directly from Latin proprius (“one's own, particular to itself”),[2][4][5] of uncertain origin.[4] Etymonline and Hoad take it from the phrase prō prīvō (“for the individual, in particular”), from prīvus (“one's own, individual”).[2][6] It is related to property, propriety and appropriate.[6][2]

Earliest recorded meaning

Belonging to oneself, one's own: before 1300 in the OED.[7] Barnhart dates propre “special, commendable” to probably before 1300, in Kyng Alisaunder,[4] and Etymonline to about 1300, “fit, apt; commendable, excellent”, sometimes ironic.[2] In grammar, of a name, it is from about 1290.[7]

Semantic evolution

“Pertaining to a person or thing in particular, distinctive” and “what is by the rules, correct” are from the early 14th century;[2] Barnhart dates “one's own” to 1303 and “appropriate, correct” to 1340.[4] “Thorough, complete” and “excellent, fine” are from the 14th century,[6] and “separate, distinct, itself”, as in the city proper, from the early 15th century.[2] The adverb, “very, exceedingly”, is from the mid-15th century, but since the 19th century it has been considered vulgar.[2] “Socially appropriate, decent, respectable” is first recorded in Swift's apology to A Tale of a Tub (1704).[4][2] In heraldry, “in its natural colours”, it is from 1572.[7] The proper noun is from the mid-15th century,[2] and the proper fraction from 1674.[4]
