View old tie (7)
I believe the answer is:
opinion
'view' is the definition.
(I know that view can be written as opinion)
'old tie' is the wordplay.
'old' becomes 'o' (abbreviation).
'tie' becomes 'pinion' (I can't explain this - if you can you should believe this answer much more).
'o'+'pinion'='OPINION'
Can you help me to learn more?
(Other definitions for opinion that I've seen before include "Conviction - point of view" , "Personal view" , "View held without positive proof" , "View, barrister's advice" , "Viewpoint" .)
