Dump the end (3)
I believe the answer is:
tip
I believe this is a double definition.
'dump' is the first definition.
(as in a rubbish tip)
'the end' is the second definition.
(tip is a kind of end)
(Other definitions for tip that I've seen before include "single piece of asparagus, perhaps" , "expected by those who wait" , "lots of rubbish" , "Topple over - hint" , "Hint or dumping ground" .)
