Term of address (5)
I believe the answer is:
madam
'term of address' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for madam that I've seen before include "How one may address a woman" , "Stuck-up girl" , "pompous young lady?" , "Formal address to a woman - precocious little girl" , "'Call Me ---' (I. Berlin)" .)
