Some rotten nuisance: the result of “all work and no play”? (5)

Ross

I believe the answer is:

ennui

I'm a little stuck... Click here to teach me more about this clue!

'of all work and no play?' is the definition.
I can't tell whether this defines the answer.

'some rotten nuisance the' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ENNUI' is hidden within 'rotten nuisance the'.

'result' is the link.

Can you help me to learn more?

(Other definitions for ennui that I've seen before include "Boredom or discontent" , "doldrums" , "What's tedious and instils such listlessness" , "boring" , "Feeling of weariness or boredom" .)
