Dock worker rode out with street girl (9)
I believe the answer is:
stevedore
'dock worker' is the definition.
('stevedore' can be a synonym of 'dock worker')
'rode out with street girl' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'with' is a charade indicator (letters next to each other).
'street' becomes 'st'.
'girl' becomes 'eve' (**).
'rode' is an anagram of 'dore'.
'st'+'eve'='steve'
'dore' put after 'steve' is 'STEVEDORE'.
(Other definitions for stevedore that I've seen before include "Dock worker" , "one working in docks" , "Unloader of shipping vessels" , "Worker who loads and unloads ships" , "One loads and unloads ships" .)
