Strive for a point of opinion (4)
I believe the answer is:
view
'opinion' is the definition.
(synonyms)
'strive for a point' is the wordplay.
'strive' becomes 'vie' (I've seen this in other clues).
'for' means one lot of letters go next to another.
'a point' becomes 'w' (W is an example).
'vie'+'w'='VIEW'
'of' acts as a link.
(Other definitions for view that I've seen before include "Opinion - vista" , "Aspect, scene" , "Watch TV, e.g." , "inspection" , "Sight - opinion" .)
