lady's title (5)
I believe the answer is:
madam
'lady's title' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for madam that I've seen before include "What you would call a female customer (or a spoiled girl!)" , "Conceited girl (colloq.)" , "Palindrome used in speaking politely to a woman" , "Term of address to a woman" , "Bossy girl" .)
