Shin (5)
I believe the answer is:
shank
'shin' is the definition.
(I have seen 'The shin ' mean 'shank' so perhaps 'shin' could also mean 'shank')
This is all the clue.
(Other definitions for shank that I've seen before include "If red, flyer" , "The shin" , "Cut of meat from lower part of foreleg" , "Cut of meat; leg" .)
