Inactivity, weariness (7)
I believe the answer is:
languor
I believe this is a double definition.
'inactivity' is the first definition.
(languor is a kind of inactivity)
'weariness' is the second definition.
(I've seen this before)
(Other definitions for languor that I've seen before include "Lack of energy" , "sloth" , "Feeling of dreaminess" , "Mental laziness" , "Pleasurable tiredness" .)
