Opposite of 'east' (4)
I believe the answer is:
west
'opposite of east' is the definition.
('west' is the opposite to 'east')
This is the entire clue.
(Other definitions for west that I've seen before include "One Direction" , "English county" , "Occident" , "The cardinal compass point of 270 degrees" , "Dog (from Argyll?)" .)
