The right animals for worthless people (7)
I believe the answer is:
rotters
This could be a double definition.
'the right animals' is the first definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'worthless people' is the second definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?
'for' is the link.
Can you help me to learn more?
(Another definition for rotters that I've seen is " Contemptible folk".)
