Did you know?
Pugnacious individuals are often looking for a fight. While unpleasant, at least their fists are packing an etymological punch. Pugnacious comes from the Latin verb pugnare (meaning "to fight"), which in turn comes from the Latin word for "fist," pugnus. Another Latin word related to pugnus is pugil, meaning "boxer." Pugil is the source of our word pugilist, which means "fighter" and is used especially of professional boxers. Pugnare has also given us impugn ("to assail by words or arguments"), oppugn ("to fight against"), and repugnant (which is now used primarily in the sense of "exciting distaste or aversion," but which has also meant "characterized by contradictory opposition" and "hostile").
