American who inhabits the White House? (6)
I believe the answer is:
eskimo
'american who inhabits the white house?' is the definition.
(eskimos live in igloos in alaska)
This is the entire clue.
(Other definitions for eskimo that I've seen before include "Native of northern Canada, Alaska etc." , "He lives in an igloo" , "Igloo-dweller" , "inhabitant of White House?" , "arctic person" .)
