Why “toparch” is a great word
TOPARCH — [Noun] The ruler or governor of a small administrative district or petty state. From the Ancient Greek τοπάρχης (topárkhēs), from τόπος (tópos, "place") + -άρχης (-árkhēs, "ruler, chief"). First attested in English in 1640. Unlike a "monarch," who commands a sovereign kingdom, or a "satrap," who governed a Persian province, a toparch is defined by the modest scale of his dominion. He is the collector of tolls at a mountain pass, the adjudicator of disputes over a damaged orchard wall, and the hereditary lord of a few sun-baked villages—a sovereign whose authority ends where the local hills begin, and whose name is a reminder that all power originates in the governance of a specific, dusty patch of earth.
Etymology
