'rubbish a beggar tidied' is the definition.
I can't judge whether this defines the answer.

'rubbish a beggar' is the wordplay.
'rubbish' is an anagram indicator (a poor quality or rubbish spelling of the letters).
'a'+'beggar'='abeggar'
'abeggar' is an anagram of 'GARBAGE'.

Can you help me to learn more?

(Other definitions for garbage that I've seen before include "Waste, refuse" , "Rubbish, waste" , "US rubbish" , "Worthless matter" , "Litter" .)
