One's fleeced a shopping centre after put-up job (5)
I believe the answer is:
llama
'job' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'one's fleeced a shopping centre after put-up' is the wordplay.
'one's fleeced' becomes 'a' (I am not sure about this - if you are sure you should believe this answer much more).
'a shopping centre' becomes 'mall' (a mall is a large shopping complex).
'after' is a charade indicator (letters next to each other).
'put up' is a reversal indicator.
'a'+'mall'='amall'
'amall' back-to-front is 'LLAMA'.
Can you help me to learn more?
(Other definitions for llama that I've seen before include "South American transport animal" , "Andean pack animal" , "Camel-like animal" , "wool supplier" , "Load-carrier" .)
