Why this word is great
MANQUELLER — [Noun] A killer of men; a manslayer or executioner. From Middle English manquellere, equivalent to man ("man") + queller ("killer, suppressor"), from Old English cwellere ("killer"). Unlike "executioner" (a sanctioned agent of the state) or "murderer" (a criminal acting in shadow), a manqueller is simply one who ends lives, unbound by law or taboo. It is the axe falling in a sunlit courtyard, the dagger slipped between ribs in a crowded market, the slow strangulation of a traitor in the dead of night—a word that speaks not of justice or guilt, but only of the act itself, and the terrible ease with which a man may cease to be.
