Woman with gold married a creep (4)
I believe the answer is:
worm
'a creep' is the definition.
(thesaurus)
'woman with gold married' is the wordplay.
'woman' becomes 'w' (abbreviation eg in Woman Police Constable).
'with' is a charade indicator (letters next to each other).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'w'+'or'+'m'='WORM'
(Other definitions for worm that I've seen before include "Wriggly creature" , "Legless creature - grovelling type" , "Squirm" , "Wretched person" , "Slither" .)
