Etymology
Origin of nonplus
First recorded in 1575–85; (noun) from Latin nōn plūs literally, “not more, no further,” that is, a state in which nothing more can be done
Explanation
To nonplus is to baffle or confuse someone to the point that they have nothing to say. Something weird and mysterious can nonplus you, like a play that is performed entirely by chickens. If you know a little French or Latin, you'll recognize that "non plus" means "no more." When something bewildering nonpluses you, there's no more you can say or do about it. A goal of getting poor grades, running with a bad crowd, and refusing to eat would leave your parents nonplussed. Sometimes people misuse nonplus to mean "unimpressed," but that's not correct: to nonplus is to puzzle, confuse, and dumbfound.
