Belgian city worker with English accent (7)
I believe the answer is:
antwerp
'belgian city' is the definition.
(Antwerp is a city in Belgium)
'worker with english accent' is the wordplay.
'worker' becomes 'ant' (worker is a type of ant).
'with' becomes 'w' (abbreviation).
'english' becomes 'E' (abbreviation).
'accent' becomes 'rp' (I am not sure about this - if you are sure you should believe this answer much more).
'ant'+'w'+'e'+'rp'='ANTWERP'
Can you help me to learn more?
(Other definitions for antwerp that I've seen before include "Province and port of Belgium" , "North Belgian port" , "Belgian city port" , "Busy Belgian port" , "harbour" .)
