Carry on by friend from avenue in the middle of Paris (7)
I believe the answer is:
palaver
'carry on' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'friend from avenue in the middle of paris' is the wordplay.
'friend' becomes 'pal' (pal is a kind of friend**).
'from' is a charade indicator (letters next to each other).
'avenue' becomes 'ave'.
'in the middle of' says to take the centre (I've seen 'in the middle' mean this).
The central letter of 'paris' is 'r'.
'pal'+'ave'+'r'='PALAVER'
'by' acts as a link.
Can you help me to learn more?
(Other definitions for palaver that I've seen before include "Song and dance" , "tedious bureaucracy" , "Hubbub; lengthy fuss" , "Rigmarole" , "idle conversation" .)
