Language of answer found in copy (5)
I believe the answer is:
carib
'language' is the definition.
(Carib is an example)
'answer found in copy' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'found in' means one lot of letters goes inside another.
'copy' becomes 'crib' (crib can mean to copy from another source).
'a' put into 'crib' is 'CARIB'.
'of' acts as a link.
(Other definitions for carib that I've seen before include "Native and language giving name to a sea" , "Native of West Indies and northern South America" , "Indian" , "S. American language" .)
