en.nui (Fr. an nwe'), n. a feeling of weariness and discontent resulting from satiety or lack of interest; boredom.
i ran across this word while i was reading aloud to the kids and since i did not know what it meant, actually, i did not even know how to say it, we looked it up in our trusty dictionary. so after reading the definition i asked the kids if they understood what it meant.
"you mean, like, 'i am feeling ennui about my schoolwork'?"
yeah. i think they get it.
