Suggestion pub open around start of evening (8)
I believe the answer is:
innuendo
'suggestion' is the definition.
(I've seen this before)
'pub open around start of evening' is the wordplay.
'pub' becomes 'inn' (an inn is a type of pub).
'open' becomes 'undo' (eg opening a bottle).
'around' means one lot of letters goes inside another.
'start of evening' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'undo' enclosing 'e' is 'uendo'.
'inn'+'uendo'='INNUENDO'
Can you help me to learn more?
(Other definitions for innuendo that I've seen before include "Slur" , "Oblique allusion" , "Malicious suggestion" , "Disparaging oblique remark" , "Indirect remark" .)
