The homeless lout really making a turnaround (5)
I believe the answer is:
hobos
'the homeless lout really making a turnaround' is the definition.
I can't tell whether this defines the answer.
'really making a turnaround' is the wordplay.
'really' becomes 'so' (both can mean 'extremely').
'making' becomes 'boh' (I can't explain this - if you can you should believe this answer much more).
'a turnaround' says the letters should be written in reverse.
'so'+'boh'='soboh'
'soboh' reversed gives 'HOBOS'.
Can you help me to learn more?
(Another definition for hobos that I've seen is " Tramps".)
