²

1. a combining form that represents the outcome of archi- in words borrowed through Latin from Greek in the Old English period; it subsequently became a productive form added to nouns of any origin, which thus denote individuals or institutions directing or having authority over others of their class ( archbishop; archdiocese; archpriest ). More recently, arch-1 has developed the senses “principal” ( archenemy; archrival ) or “prototypical” and thus exemplary or extreme ( archconservative ); nouns so formed are almost always pejorative.
