In Paris, some trouble to follow for each wild ruffian (9)
I believe the answer is:
desperado
'wild ruffian' is the definition.
(I've seen this before)
'in paris some trouble to follow for each' is the wordplay.
'in paris' becomes 'des' (I can't explain this - if you can you should believe this answer much more).
'some trouble' becomes 'ado' (both can mean bother or commotion).
'to follow' says to put letters next to each other (some letters go after or follow others).
'for each' becomes 'per' (per person).
'ado' after 'per' is 'perado'.
'des'+'perado'='DESPERADO'
Can you help me to learn more?
(Other definitions for desperado that I've seen before include "Bold outlaw on the American frontier" , "Gangster" , "Reckless person" , "Bravo" , "Wild ruffian" .)
