Liberal European circle supports end of inane ogling (7)
I believe the answer is:
leering
'ogling' is the definition.
(I've seen this before)
'liberal european circle supports end of inane' is the wordplay.
'liberal european' becomes 'le' (this might be a standard abbreviation which I don't know about).
'circle' becomes 'ring' ('ring' can be a synonym of 'circle').
'supports' says to put letters next to each other (bottom letters provide a support for the top ones).
'end of' indicates one should take the final letters.
The final letter of 'inane' is 'e'.
'ring' after 'e' is 'ering'.
'le'+'ering'='LEERING'
Can you help me to learn more?
(Other definitions for leering that I've seen before include "appearing lascivious" , "Ogling" , "giving the glad eye" , "Looking suggestively" , "Gazing lasciviously" .)
