Languid, apathetic (8)
I believe the answer is:
listless
I believe this is a double definition.
'languid' is the first definition.
(synonyms)
'apathetic' is the second definition.
(I've seen this before)
(Other definitions for listless that I've seen before include "Tells sis to be lacking in energy" , "'Lethargic, spiritless (8)'" , "Sluggish" , "Uninterested" , "without enthusiasm" .)
