Oz mob baling out - mystifying (11)
I believe the answer is:
bamboozling
'mystifying' is the definition.
Although both the answer and definition are present participle verbs, I cannot see how they can define each other.
'oz mob baling out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'oz'+'mob'+'baling'='ozmobbaling'
'ozmobbaling' with letters rearranged gives 'BAMBOOZLING'.
Can you help me to learn more?
(Other definitions for bamboozling that I've seen before include "Hoodwinking" , "Fooling" .)
