Nice woman? (6)

I believe the answer is:

madame

I'm a little stuck... Click here to teach me more about this clue!

'nice woman?' is the definition.
('woman' in French, eg in Nice)

'nice woman?' is the wordplay.
'nice' becomes 'mad' (I can't justify this - if you can you should give a lot more credence to this answer).
'woman?' becomes 'Ame'.
'mad'+'ame'='MADAME'

Can you help me to learn more?

(Other definitions for madame that I've seen before include "Woman of refinement" , "Flaubert novel" , "French Mrs" , "French married woman" , "Book by Flaubert" .)

I've seen this clue in The Telegraph.
