Berlin, Germany - see some hang about (6)
I believe the answer is:
linger
'hang about' is the definition.
(I've seen this before)
'berlin germany see some' is the wordplay.
'see some' indicates the answer is hidden within the clue.
'LINGER' is hidden within 'berlin germany'.
(Other definitions for linger that I've seen before include "Delay departure" , "Procrastinate" , "Hang back awhile" , "Stay on as if reluctant to leave" , "Stay behind" .)
