Make churchmen look like monkeys? (8)
I believe the answer is:
primates
'monkeys?' is the definition.
(monkey is a kind of primate)
I don't 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 "Archbishops or apes" , "Apes; bishops" , "Lemurs, apes, men, etc." , "Animals including monkeys and apes" , "some leading churchmen" .)
