Vagrant fellow in the city (7)
I believe the answer is:
hoboken
'the city' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'vagrant fellow' is the wordplay.
'vagrant' becomes 'hobo' (I've seen this before).
'fellow' becomes 'ken' (I can't justify this - if you can you should believe this answer much more).
'hobo'+'ken'='HOBOKEN'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for hoboken that I've seen before include "City in New Jersey (or part of Antwerp)" , "Sinatra's NJ birthplace" .)
