What does archdiocesan mean?
Archdiocesan describes anything pertaining to an archdiocese — the principal ecclesiastical district in many Christian churches, presided over by an archbishop. As an adjective, it appears most often in official and administrative language: archdiocesan offices, archdiocesan schools, archdiocesan councils, and archdiocesan newspapers all fall under the direct authority of an archdiocese rather than an individual parish. In American Catholic usage the term also functions as a noun, where an 'archdiocesan' denotes a priest who serves directly under an archbishop instead of joining a religious order such as the Jesuits or Dominicans. The word carries a formal, institutional tone and is rarely heard outside religious, legal, or journalistic coverage of church affairs. Its roots run deep: it derives from 'diocese,' ultimately from the Greek 'dioikēsis' meaning administration or household management — the same lineage that produced the modern word 'economics.'
Of or relating to an archdiocese, its clergy, administration, or institutions.
"All parish finances must be reported to the archdiocesan finance council each quarter."
Typically capitalized when part of an official title (e.g., Archdiocesan Synod); otherwise lowercase.
(Chiefly in American Catholic usage) A member of the clergy who belongs to and serves under an archdiocese, as opposed to a religious order.
"As an archdiocesan, Father Byrne was incardinated into the archdiocese of Chicago rather than into a religious congregation."
This noun sense is informal-to-formal Catholic jargon, mostly confined to North America; elsewhere the adjective sense predominates almost exclusively.
Plural applies only to the noun sense referring to clergy belonging to an archdiocese.
"The retreat brought together archdiocesans from across the province for a week of formation."
Every time you say 'archdiocesan,' you're unknowingly using a word whose roots trace back to the ancient Greek word for 'household management' — the same root that gave us 'economics.'

Etymology of archdiocesan
The word derives from 'archdiocese,' formed by prefixing the Latin-derived Greek 'arch-' meaning chief or principal onto 'diocese.' 'Diocese' itself traces back through Latin 'dioecesis' to Greek 'dioikēsis,' meaning administration or government of a household, from 'dioikein' (to manage a house), rooted in 'oikos' (house) — the same Greek root underlying 'economics' and 'ecology.' English borrowed 'diocese' from Latin in medieval times, and the compound 'archdiocese' emerged later to denote the larger jurisdiction of an archbishop, with 'archdiocesan' arising as its adjectival derivative.
How archdiocesan is actually used
Primarily encountered in formal, religious, or administrative contexts within Roman Catholic, Eastern Orthodox, and some Anglican churches. The noun use ('an archdiocesan') is chiefly North American Catholic parlance referring to secular clergy under an archbishop's jurisdiction.
