Wild as well, moving south (7)
I believe the answer is:
lawless
'wild' is the definition.
(I've seen this in another clue)
'as well moving south' is the wordplay.
'moving' indicates anagramming the letters (letters are moved around).
'south' becomes 's' (abbreviation).
'as'+'well'='aswell'
'aswell' anagrammed gives 'lawles'.
'lawles'+'s'='LAWLESS'
(Other definitions for lawless that I've seen before include "Anarchy" , "Slew Sal for being criminal" , "Wild wild" , "Unruly - anarchic" , "disobedient" .)
