Suffer in Berlin and consequently in Rome (7)
I believe the answer is:
undergo
'suffer' is the definition.
(undergoing is a kind of suffering)
'in berlin and consequently in rome' is the wordplay.
'in berlin and' becomes 'und' ('and' in German).
'consequently in rome' becomes 'ergo' (I am not sure about this - if you are sure you should believe this answer much more).
'und'+'ergo'='UNDERGO'
Can you help me to learn more?
(Other definitions for undergo that I've seen before include "Experience - bear" , "Stand" , "Endure - urged on (anag)" , "Suffer, experience" , "Withstand" .)
