US agent gives name, with a bow (5)
I believe the answer is:
narco
'us agent' is the definition.
(I've seen this before)
'name with a bow' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'with' means one lot of letters go next to another.
'a bow' becomes 'arco' (I've seen this before).
'n'+'arco'='NARCO'
'gives' acts as a link.
(Other definitions for narco that I've seen before include "Drugs agent (US slang)" , "Member of US drugs squad" , "American drug agent" , "Drug trafficker" .)
