Primate and bishop with rings round head (6)
I believe the answer is:
bonobo
'primate' is the definition.
(bonobo is a kind of primate)
'bishop with rings round head' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'with rings' becomes 'oo' (multiple circles. I am not sure about the 'with' bit.).
'round' indicates putting letters inside.
'head' becomes 'nob' (slang term for the head).
'oo' enclosing 'nob' is 'onobo'.
'b'+'onobo'='BONOBO'
'and' is the link.
Can you help me to learn more?
(Other definitions for bonobo that I've seen before include "Small chimpanzee" , "our nearest relative" .)
