Fleshy part of the ear (4)
I believe the answer is:
lobe
'fleshy part of the ear' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for lobe that I've seen before include "flap" , "Appendage to ear" , "Leaf division" , "Fleshy part of the ear (4)" , "Piece of ear" .)
