Partner of monsieur (6)

Ross

I believe the answer is:

madame

(Other definitions for madame that I've seen before include "Proprietress of a brothel" , "Married woman abroad" , "A French-speaking woman" , "Title for a Frenchwoman" , "Flaubert novel" .)

I've seen this clue in The Sunday Times and The Times.
