Cadger is terrible person shamed (8)
I believe the answer is:
disgrace
'person shamed' is the definition.
I can't judge whether this definition defines the answer.
'cadger is terrible' is the wordplay.
'terrible' is an anagram indicator.
'cadger'+'is'='cadgeris'
'cadgeris' anagrammed gives 'DISGRACE'.
Can you help me to learn more?
(Other definitions for disgrace that I've seen before include "scandalous" , "scandal" , "State of dishonour" , "Loss of honour" , "Bring shame upon" .)
