Etymology

It is inherited from Middle English proprietarie,[2][3][4] partly borrowed from Anglo-Norman proprietarie (“owner”) and Middle French proprietaire (now French propriétaire), and partly borrowed from Latin proprietārius (“owner; of an owner”).[5][4][3][6][7] The Latin noun is recorded from the 2nd century AD; in post-classical Latin it was also an adjective, and it was used of a monk who held private property from the 9th century and of the holder of an appropriated benefice from 1439.[5] It is formed from proprietās (“ownership; property”) and the suffix -ārius,[5][2][6] and the noun in turn from proprius (“one's own”), the source of proper.[3][8][9] Hoad notes that proprietor (17th century) is an alteration of proprietary with a different suffix.[10]

Earliest recorded meaning

As a noun, in church history, the holder of an appropriated benefice: 1446.[5] Barnhart dates the noun to 1401, for a person caught up in worldly goods to the neglect of devotion,[4] and Etymonline to about 1400.[6]

Semantic evolution

The word began as a term of the church: a member of a religious order who broke the vow of poverty by holding property, or more widely a selfish, worldly person (about 1450 to 1632).[5][7][4] The adjective likewise first meant property-owning, used of clerics who had more worldly goods than they needed (about 1450).[5][6][4] The general sense "an owner" is recorded from 1473 to 1852,[5][4] and the adjective "held in private ownership" from 1589, in Puttenham.[5][4][2] From 1637 in the American colonies a proprietary was a person granted rights of government over a colony;[5][6] such proprietary colonies (from 1704) were distinguished from charter and royal colonies.[5][6] Johnson (1755) defined the adjective as belonging to a certain owner, and the noun as a possessor in his own right.[11] From 1785 a proprietary drug or medicine was one whose making or sale was restricted to particular people, later one sold under a trade name.[5][9] In American use the noun meant such a drug from 1901.[5]
