Cheap rasp thrown into the rubbish (9)
I believe the answer is:
scrapheap
'the rubbish' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'cheap rasp thrown' is the wordplay.
'thrown' is an anagram indicator.
'cheap'+'rasp'='cheaprasp'
'cheaprasp' anagrammed gives 'SCRAPHEAP'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for scrapheap that I've seen before include "Junk" , "Waste pile" , "Pile of discarded metal" , "Cap phrase about mound of waste material" , "Pile of discards" .)
