Zones in Far East (5)
I believe the answer is:
areas
'zones' is the definition.
(I've seen this before)
'in far east' is the wordplay.
'in' indicates the answer is hidden within the clue.
'AREAS' is hidden within 'far east'.
(Other definitions for areas that I've seen before include "Geographical regions" , "Zones" , "Localities" , "Places" , "Spaces covered by two-dimensional surfaces" .)
