Tedium, ennui (7)
I believe the answer is:
boredom
This clue is a double definition.
'tedium' is the first definition.
(I know that tedium can be written as boredom)
'ennui' is the second definition.
(I know that ennui can be written as boredom)
(Other definitions for boredom that I've seen before include "Overseers" , "weary idleness" , "Ennui in bedroom" , "no interest" , "Tedium, ennui" .)
