prior

Etymology and origin of the English word prior

The noun prior, a monastic superior, came into Old English from Medieval Latin, while the adjective prior, “earlier”, was borrowed directly from Latin in the 18th century; both go back to Latin prior “former, superior”.[1][2][3]

Etymology

The monastic superior is inherited from Middle English priour, prior,[1][3] from late Old English prior,[5][1] borrowed from Medieval Latin prior (“superior officer”),[1][5] in Late Latin “administrator, predecessor”,[3] a noun use of Latin prior (“former, superior”).[1][5] It was reinforced in Middle English by Old French priur, prior (modern prieur).[1][2]

Earliest recorded meaning

A superior officer of a religious house or order: 1093,[1][6] with the Middle English form first recorded in 1123.[1]

Semantic evolution

In an abbey the prior ranks next below the abbot, and in a priory he is the head.[6][7] In some former Italian republics, such as Florence, the priors were chief magistrates, from 1604.[6] A superior in general is from about 1380, after Latin prior in the Vulgate, and in commerce the head of a firm from 1853, now rare.[6] Prioress is from about 1300 and priory from the 13th century.[1][2] In American English prior is also short for a prior arrest or conviction, from 1990.[5]

Etymology

The adjective is borrowed from Latin prior (“former, previous, first; superior”),[5][1] the comparative of Old Latin prī “before”,[5][1][3] from Proto-Indo-European *per- (“forward, before, first”).[5] It is related to prae (“before”) and prīscus (“ancient”).[1][3]

Earliest recorded meaning

Preceding in time or order, earlier: 1714, often followed by to.[6][1][5] Merriam-Webster dates the adjective to 1607.[3]

Preceding in importance is a further sense.[7][8] Prior to is used as a preposition meaning “before”, adverbially by 1706.[5] Priority is much older, from about 1385.[1]
