You'll find nothing to hold down a point of view (7)
I believe the answer is:
opinion
'a point of view' is the definition.
(I've seen this before)
'you'll find nothing to hold down' is the wordplay.
I cannot really see how this works, but
'nothing' could be 'o' (looks like zero - 0) and 'o' is located in the answer.
'hold' could be 'pinion' (pinioning is a kind of holding) and 'pinion' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for opinion that I've seen before include "View, judgement" , "school of thought" , "Point of view or thought on something" , "A view held, what one thinks" , "A view held as probable - well, that's mine" .)
