Part of the Far East (4)
I believe the answer is:
area
'part' is the definition.
(area is a kind of part)
'of the far east' is the wordplay.
'of' says the answer is hidden in the clue.
'AREA' is hidden in the letters of '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" .)
