Gloria's arranged housing for eastern women here (8)
I believe the answer is:
seraglio
'eastern women here' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'gloria's arranged housing for' is the wordplay.
'arranged' is an anagram indicator (letters rearranged).
'housing' means one lot of letters goes inside another.
'for' becomes 'se' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'gloria' is an anagram of 'raglio'.
'raglio' placed around 'se' is 'SERAGLIO'.
Can you help me to learn more?
(Other definitions for seraglio that I've seen before include "Gaoler is found in kind of harem" , "Female apartments" , "female quarters" , "Group of women" , "single-sex accommodation" .)
