Primates in tapestry (4)
I believe the answer is:
apes
'primates' is the definition.
(ape is a kind of primate)
'in tapestry' is the wordplay.
'in' indicates a hidden word.
'APES' is hidden in the letters of 'tapestry'.
(Other definitions for apes that I've seen before include "Imitates like primates" , "Peas (anag)" , "Parrots" , "Imitates in every aspect" , "Copies the primates?" .)
