Etymology

Origin of ennui

First recorded in 1660–70; from French: “boredom”; Old French a(n)nui, enui “displeasure”; see annoy

Explanation

The French word ennui describes a feeling that combines tiredness and boredom. Ennui is one version of "the blahs." Though it sounds a little fancy — maybe because it comes from French — ennui is a common feeling that everybody experiences: being bored and tired. School and work fill lots of people with ennui. A terrible TV show could create ennui. If you feel like your life is going nowhere, ennui could set in. When you're feeling ennui, you might as well take a nap, because you're too drowsy and uninterested to do much of anything else.
