Part of the Far East (4)
I believe the answer is:
area
'part' is the definition.
(I know that area is a type of body part)
'of the far east' is the wordplay.
'of' indicates a hidden word.
'AREA' is hidden within 'far east'.
(Other definitions for area that I've seen before include "District; locale" , "Locality" , "Space occupied by something" , "environs" , "Part of a building, city etc" .)
