Variety of aster eaten by animals (5)
I believe the answer is:
tares
'eaten by animals' is the definition.
Although both the answer and definition are plural nouns, I can't understand how they can define each other.
'variety of aster' is the wordplay.
'variety of' indicates an anagram.
'aster' with letters rearranged gives 'TARES'.
Can you help me to learn more?
(Other definitions for tares that I've seen before include "Stare at the vetches" , "The weights of packaging" .)
