Delegates of a vet's enterprise at sixes and sevens (15)
I believe the answer is:
representatives
'delegates' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'a vet's enterprise at sixes and sevens' is the wordplay.
'at sixes and sevens' indicates anagramming the letters.
'a'+'vets'+'enterprise'='avetsenterprise'
'avetsenterprise' is an anagram of 'REPRESENTATIVES'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for representatives that I've seen before include "10 [HOUSE] of these in US" , "Officers" , "MPs!" .)
