Dome-shaped Inuit houses (6)
I believe the answer is:
igloos
'dome-shaped inuit houses' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for igloos that I've seen before include "Inuit houses made from blocks of snow" , "Ice houses for Eskimos" , "Houses for Inuits" , "Arctic homes" , "homes up north" .)
