A beggar sorted out the contents of the bin (7)
I believe the answer is:
garbage
'contents of the bin' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'a beggar sorted out' is the wordplay.
'sorted out' indicates anagramming the letters.
'a'+'beggar'='abeggar'
'abeggar' anagrammed gives 'GARBAGE'.
'the' is the link.
Can you help me to learn more?
(Other definitions for garbage that I've seen before include "'Refuse, rubbish (7)'" , "Worthless matter" , "Rubbish - invalid computer data" , "Refuse - worthless talk" , "Nonsense!" .)
