Land where the winter ends with a cloudburst (7)
I believe the answer is:
terrain
This might be a double definition.
'land' is the first definition.
(terrain is land or territory)
'where the winter ends with a cloudburst' is the second definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for terrain that I've seen before include "A stretch of land for trainer" , "Type of countryside" , "Land with respect to its features" , "Piece of ground" , "Physical features of a tract of land" .)
