Views allowing stone to be overturned (8)
I believe the answer is:
thoughts
'views' is the definition.
('thought' can be a synonym of 'view')
'allowing stone to be overturned' is the wordplay.
'allowing' becomes 'though' (I can't explain this - if you can you should give a lot more credence to this answer).
'stone' becomes 'st' (abbreviation).
'to be overturned' shows that the letters should be reversed in order.
'st' in reverse letter order is 'ts'.
'though'+'ts'='THOUGHTS'
Can you help me to learn more?
(Other definitions for thoughts that I've seen before include "Ideas, musings" , "They are in my mind" , "Notions" , "Cogitations" , "Ideas and opinions (8)" .)
