Pronunciation

Forms

diocèse m (plural diocèses)[1] Old French dyocheze, diocise, dioces; feminine until the 16th century.[2][3][4]

Etymology

It is borrowed from Latin dioecēsis (“administrative district”), used in Christian Latin for the district of a bishop.[2][5][4] The Latin word is from Ancient Greek διοίκησις (dioíkēsis, “housekeeping, administration, province”), from διοικέω (dioikéō, “to manage, administer”), formed with a prefix on οἴκησις (oíkēsis), from οἰκέω (oikéō, “to dwell, manage”), from οἶκος (oîkos, “house”).[5][3][1] The Greek root is also that of œcuménique.[5]

The word was feminine, like its Latin source, until the 16th century.[2][3][4] Compare Italian diocesi, Portuguese diocese and Old Occitan diocesa.[3]

Earliest recorded meaning

The TLFi's first record is dyocheze in the Miracles of Gautier de Coinci (about 1223), for the district administered by a bishop;[2] the DHLF and Bloch and Wartburg date the word to about 1180.[5][4]

Semantic evolution

The word entered French as a term of canon law.[5] A general sense, “place where something is administered”, recorded by Estienne in 1549, did not last.[2][5] In the 17th century it was taken again from Latin as a term of Roman history, for an administrative district of the late Roman Empire, first feminine (1678) and then masculine (1680).[2][5]

The adjective diocésain was formed in 1265 from Christian Latin diocesanus.[5][4]
