They include man, monkeys and archbishops (8)
I believe the answer is:
primates
'archbishops' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for primates that I've seen before include "some leading churchmen" , "Animals including monkeys and apes" , "Archbishops or apes" , "Apes; bishops" , "Lemurs, apes, men, etc." .)
