Woman's complaint when mother leaves (4)
I believe the answer is:
lady
'woman's' is the definition.
(lady is a kind of woman)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lady that I've seen before include "Title for a knight's wife" , "See 19" , "Female peer" , "High-class woman" , "older female" .)
