Did you know?

Impugn, pugnacious, pugilist: them’s fightin’ words, literally. All three words trace back to the Latin noun pugnus, meaning “fist.” Though they floated like butterflies down different paths into English from that shared source, each stings like a bee (so to speak) in its own way. The noun pugilist refers to a fighter or boxer, while the adjective pugnacious describes someone showing a readiness or desire to fight or argue. The verb impugn today has belligerent implications, albeit of the verbal jousting kind, but in its earliest known English uses in the 1300s, impugn could refer to a physical attack (as in, “the troops impugned the city”) as well as to assaults involving verbal contradiction or dispute. Over time, though, the sense of literal battling has become obsolete while the “assailing by words or arguments” sense has endured.
