Primate in tapestry (3)
I believe the answer is:
ape
'primate' is the definition.
(large primate)
'in tapestry' is the wordplay.
'in' says the answer is hidden in the clue.
'APE' is hidden within 'tapestry'.
(Other definitions for ape that I've seen before include "Wild animal" , "Copy - primate" , "Mimic the primate" , "Anthropoid primate" , "intelligent creature" .)
