Crossword Genius

Kept woman as cure, not remedy (9)

Ross

I believe the answer is:

'kept woman' is the definition.
(courtesan is a kind of kept woman)

'as cure not remedy' is the wordplay.
'remedy' is an anagram indicator (I've seen this in other clues).
'as'+'cure'+'not'='ascurenot'
'ascurenot' is an anagram of 'COURTESAN'.

(Other definitions for courtesan that I've seen before include "loose woman", "lover", "odalisque", "High-class prostitute", "Kept woman".)

I've seen this clue in Sydney Morning Herald.
