Muslim women's quarters (5)
I believe the answer is:
harem
'muslim women's quarters' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for harem that I've seen before include "Her ma (anag)" , "Living quarters for wives and concubines" , "Women's quarters in a Muslim house" , "Quarters occupied by women by Muslim household" , "Quarters for women in Muslim household, a seraglio" .)
