Etymology
The word "demesne" entered English from Anglo-Norman French demesne or demeine, meaning "belonging to a lord." This, in turn, derived from Latin dominicus, meaning "belonging to a master" (dominus). The spelling was altered in Anglo-French by association with Old French mesne (from Latin medianus), which referred to land held by a lord of the manor, not sublet to tenants. The literal core is "land held from (a lord)" or "land of the master," which evolved from the concrete concept of a lord's private estate to the more abstract sense of a domain or sphere of control.
