Conical shelter (6)
I believe the answer is:
teepee
'conical shelter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for teepee that I've seen before include "Wigwam" , "Conical tent of American Indians" , "Conical American Indian tent" , "N. American native tent" , "Tent used by American aborigines" .)
