Canopy for shelter (6)
I believe the answer is:
awning
'canopy for shelter' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for awning that I've seen before include "It keeps sun and rain off a shop window" , "Canvas covering in front of shop" , "Sunshade" , "Canvas cover over a shop entrance" , "Canvas shade" .)
