See me wrapped up in warm coat, but only part of leg (5)
I believe the answer is:
femur
'only part of leg' is the definition.
('femur' is part of 'leg')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for femur that I've seen before include "Thigh bone" , "Thighbone" , "Bone in leg" , "Large bone" , "Part of leg" .)
