Forms
dioecēsānus (feminine dioecēsāna, neuter dioecēsānum); first/second-declension adjective[1] Medieval spellings include diocēsānus, diocesianus and dyocesanus.[2][3][4]
Etymology
It is formed from Latin dioecēsis + -ānus.[1][5]
Earliest recorded meaning
Köbler dates its first record to the Theodosian Code of 438;[2] the TLL cites it from the interpretation of a law of 376 in the Code, where the bishop calls together the priests of his diocese.[5]
Semantic evolution
Isidore of Seville has it of the churches of a diocese.[5] In Medieval Latin it meant “diocesan” and “situated in a given diocese”, and as a noun a suffragan bishop in relation to his metropolitan, the bishop who governs a diocese, and in the plural the faithful of a diocese.[4] British writers speak of diocesan law and of the episcopus dioecesanus;[6] Du Cange cites the diocesan bishop from a synod at Bergamo in 1311,[7] and Hungarian documents use it from the 13th century.[3]
English diocesan came from Old French and directly from Medieval Latin in the mid-15th century.[8]
