Etymology

The word "ennui" entered English from French in the 18th century, retaining its original spelling. It traces back to the Latin inodiare ("to make loathsome"), combining in- (intensifier) and odium ("hatred"). The French ennui evolved from enuier, meaning "to annoy" or "to bore," reflecting a shift from active irritation to passive weariness. The modern sense captures a sophisticated, existential boredom tied to idleness or monotony.
