View as a good head, all round (7)
I believe the answer is:
opinion
'view' is the definition.
(synonyms)
'a good head all round' is the wordplay.
'a good' becomes 'pi' (I've seen this in other clues).
'head' becomes 'onion' (I've seen this before).
'all round' means one lot of letters goes inside another.
'pi' placed inside 'onion' is 'OPINION'.
'as' acts as a link.
(Other definitions for opinion that I've seen before include "impression" , "'Judgment, view (7)'" , "View, judgement" , "Estimation" , "Conviction - point of view" .)
