diocesan

Etymology

It is inherited from Middle English diocesan, also spelled diosesan,^[2] borrowed from Middle French diocesain,^[3][1][4][5] and partly directly borrowed from Medieval Latin diocesanus.^[6][7][2] The French adjective, recorded from the 15th century, is formed from diocese with the suffix that English has as -an;^[3][6] the medieval Latin form is recorded in 1311.^[3] Merriam-Webster Unabridged takes the medieval Latin word as an alteration of Late Latin dioecesanus, from dioecesis and the suffix Latin -ānus;^[7][5] the OED notes that a regular Latin derivative would have kept the -i- of the stem, as Old French dyocesiien (1332) does.^[3] The Latin noun meant a governor's district and later a bishop's jurisdiction; it comes from Ancient Greek διοίκησις (dioíkēsis, “housekeeping, administration”), from διοικέω (dioikéō, “to keep house, administer”), formed from δια- (dia-, “through, thoroughly”) and οἰκέω (oikéō, “to inhabit, manage”),^[3][8] from οἶκος (oîkos, “house”).^[8]

Earliest recorded meaning

The bishop of a diocese: before 1443, in a petition to the Chancery that calls the Bishop of Llandaff "Diocesan of the saide Priorie".^[2] The OED's first quotation is from Jacob's Well, about 1450,^[3] and Etymonline dates both adjective and noun to the mid-15th century.^[6]

Semantic evolution

The word was first used of the bishop, the bishop diocesan who had jurisdiction over a diocese, both as a noun and as an adjective after bishop.^[2][3] From 1502 the noun could also mean one of the clergy or people of a diocese,^[3] a sense Merriam-Webster Unabridged now labels archaic.^[7] The general adjective, of or relating to a diocese, is recorded from 1530.^[3] Johnson (1755) defined the noun as a bishop in relation to his own clergy or flock, quoting the Tatler.^[9] In modern Catholic usage diocesan priests, who belong to a diocese and are subject to its bishop, are contrasted with religious priests, who belong to an order.^[7]
