A weary, listless flatness — not 'nothing to do' but 'nothing worth doing'. The state of finding existence itself faintly tiresome.
No coiner — borrowed from French; in English from the 1660s.
// Where it sits
Only the right-hand end resists being fixed by a suggestion.
What it really means
English already has this word. It is annoy.
Ennui and annoy are doublets — the same French word, borrowed into English twice, centuries apart. One arrived early and got worn down into a plain everyday verb. The other arrived in the 1660s, kept its French spelling and its French mouth, and became the most self-consciously elegant word for feeling flat that English possesses.
Which tells you something the usual definition hides.
The root is Latin in odio — in hatred, from odium — through Late Latin inodiare, to make loathsome. So the feeling at the bottom of ennui is not emptiness. It is weary disgust.
That is the difference from boredom, and it is a real one rather than a matter of register. Boredom is situational: you have nothing to do, and something to do would fix it. It is a complaint about this afternoon.
Ennui has been offered things to do and found them wanting. It is a complaint about everything, and it survives the cure — which is why the useful test is not am I bored? but if someone offered me something genuinely interesting right now, would it help?
If the answer is yes, that is boredom, and it is easy.
One small correction to the word's reputation. It is filed as a Romantic word — Byron, Baudelaire, pale men in the nineteenth century being tired of the world. But English had borrowed it by the 1660s and naturalised it by 1758, a century or more before that vogue. The poets did not import it. They found it waiting.
Its nearest neighbours are worth knowing, because they mark out a territory English otherwise leaves unnamed: acedia, the old monastic listlessness that was once counted a sin, and Weltschmerz, world-pain.
This page is educational and not a diagnosis. Ennui is a literary word, not a clinical one — if flatness or loss of interest has lasted weeks, a doctor, therapist or counsellor is the right place to take it.
Where it comes from
ANNOY and ENNUI are doublets — the same French word borrowed into English twice, centuries apart. The root feeling is loathing, not emptiness.
Myths & misconceptions
Ennui is just a fancy French word for boredom.
Its root is Latin IN ODIO, 'in hatred' — the same root that produced English ANNOY. Etymologically it names weary DISGUST rather than under-stimulation. Boredom wants something to do; ennui has been offered things to do and found them wanting.
It's a Romantic-era coinage that arrived with Byron and Baudelaire.
The English borrowing dates to the 1660s and full naturalisation to 1758 — a century or more before the literary vogue it is now associated with. The poets found the word waiting for them.
Compare & contrast
Ennui vs boredom
Boredom is situational and an event cures it. Ennui is dispositional and survives the event — it is glossed as a listlessness CAUSED BY boredom, which makes boredom the cause and ennui the residue.

Questions people ask
- Is ennui the same as depression?
- No. In ordinary use it simply means weariness and boredom — a descriptive word, often reached for in literary and aesthetic contexts, carrying no diagnostic meaning. This page is educational and not a diagnosis — persistent loss of interest is worth taking to a clinician rather than to a dictionary.
- Why does it sound so French?
- Because it is. English kept the French spelling and pronunciation rather than anglicising it — unlike its own twin, ANNOY, which is the same word borrowed centuries earlier and worn down into English.
- What are its near neighbours?
- Acedia and Weltschmerz — a cluster about weariness with the world rather than with an afternoon.
