Point of view established (4)
I believe the answer is:
west
'point' is the definition.
(I know that west is a type of cardinal compass point)
'of view established' is the wordplay.
'of' says the answer is hidden in the clue.
'WEST' is hidden within 'view established'.
(Other definitions for west that I've seen before include "'Go ___ , young man'" , "One Direction" , "Occident" , "Dog (from Argyll?)" , "Small white dog" .)
