Periods for which accommodation is required (8)
I believe the answer is:
quarters
'periods' is the definition.
(quarter is a kind of period)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for quarters that I've seen before include "Rooms, lodgings" , "Four equal parts" , "Subdivides" , "American cash" , "Change for American" .)
