Member in uncertain position when love is missing (4)
I believe the answer is:
limb
'member' is the definition.
(member can mean a limb)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for limb that I've seen before include "Bough" , "Tentacle" , "Branch - arm - leg" , "Wing, perhaps" , "arm, perhaps" .)
