Greek house's storage space? (5)
I believe the answer is:
attic
This could be a double definition.
'greek' is the first definition.
(from ancient Athens or Attica)
'storage space?' is the second definition.
(an attic may be used as storage space)
'house's' is the link.
This may not be right. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for attic that I've seen before include "Room at the top of a house" , "cockloft" , "Room inside a building's roof space" , "room with lots of junk?" , "from Greece" .)
