Tedium being buttonholed by drunken nuisance (5)
I believe the answer is:
ennui
'tedium' is the definition.
(I know that tedium can be written as ennui)
'buttonholed by drunken nuisance' is the wordplay.
'ENNUI' is hidden in amongst the letters.
But, I am not sure how the hidden word is indicated.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for ennui that I've seen before include "tiredness" , "World-weariness" , "depression" , "having nothing to do" , "Feeling of listlessness" .)
