Plural of deanery; the residences, offices, or administrative centers of deans, particularly in church or academic settings.
From deanery (the position, territory, or residence of a dean) + -ies (plural). Deanery comes from dean + -ery (place or domain), with roots in Latin decanus (leader of ten).
Medieval deaneries were often substantial properties because deans needed impressive residences to host visiting clergy and scholars—in essence, they were the hotel networks of the medieval church.
