Arctic homes initially interest grand ladies and gents (6)
I believe the answer is:
igloos
'arctic homes' is the definition.
(I've seen this before)
'initially interest grand ladies and gents' is the wordplay.
'initially' indicates taking the first letters.
'ladies and gents' becomes 'loos' (toilets).
The first letters of 'interest grand' is 'ig'.
'ig'+'loos'='IGLOOS'
(Other definitions for igloos that I've seen before include "Inuit houses made from blocks of snow" , "Ice houses for Eskimos" , "Dome-shaped Inuit houses" , "Ice homes for eskimos" , "Houses of snow and ice" .)
