Member's loveless dance (4)
I believe the answer is:
limb
This clue might be a double definition.
'member's' is the first definition.
(limb is a kind of member)
'loveless dance' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
Can you help me to learn more?
(Other definitions for limb that I've seen before include "Wing, perhaps" , "A supporter" , "Human's extension" , "Branch of a tree (risky to go out on)" , "Part of body or branch of tree" .)
