Meat minced by the right circus worker
I believe the answer is:
tamer
'circus worker' is the definition.
(I've seen this in another clue)
'meat minced by the right' is the wordplay.
'minced' is an anagram indicator.
'by' says to put letters next to each other.
'the right' becomes 'r' (common abbreviation).
'meat' anagrammed gives 'tame'.
'tame'+'r'='TAMER'
(Other definitions for tamer that I've seen before include "Less arousing, exciting" , "less offensive?" , "Animal trainer" , "Less wild" .)
