Female quarters no learner in Harlem (5)
I believe the answer is:
harem
'female quarters' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for harem that I've seen before include "Muslim's wives" , "Separate women's quarters" , "Women's quarters in a Muslim house" , "Place for women" , "Living quarters for wives and concubines" .)
