Knight undressed noblewoman (4)
I believe the answer is:
lady
'noblewoman' is the definition.
(I know that noblewoman can be written as Lady)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for lady that I've seen before include "High-class woman" , "Female peer" , "See 20" , "See 2" , "mature woman" .)
