Dump waste (6)
I believe the answer is:
desert
This clue could be a double definition.
'dump' is the first definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'waste' is the second definition.
(a desert may be described as a wasteland)
Can you help me to learn more?
(Other definitions for desert that I've seen before include "desolate place" , "See 33 Down" , "merit and a > quiet place" , "Merit < leave" , "Abandon; dull area" .)
