Appropriate opinion (4)
I believe the answer is:
take
I believe this clue is a double definition.
'appropriate' is the first definition.
(I've seen this before)
'opinion' is the second definition.
(Other definitions for take that I've seen before include "Teak (anag.)" , "Snatch" , "Procure" , "Perspective" , "Steal; subtract" .)
