Differ about entire broadcast concerning treatment of animals (10)
I believe the answer is:
veterinary
'treatment of animals' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'differ about entire broadcast' is the wordplay.
'differ' becomes 'vary' (varying is a kind of differing).
'about' is an insertion indicator.
'broadcast' is an anagram indicator (letters scattered or cast around).
'entire' anagrammed gives 'eterin'.
'vary' going around 'eterin' is 'VETERINARY'.
'concerning' acts as a link.
Can you help me to learn more?
(Other definitions for veterinary that I've seen before include "Animal doctor" , "Like some surgeons" .)
