It's turned up in nasty cheap copy (8)
I believe the answer is:
pastiche
'copy' is the definition.
(thesaurus)
'it's turned up in nasty cheap' is the wordplay.
'turned up' says the letters should be written backwards.
'in' indicates putting letters inside.
'nasty' indicates an anagram.
'its' written backwards gives 'sti'.
'cheap' anagrammed gives 'pache'.
'sti' going inside 'pache' is 'PASTICHE'.
(Other definitions for pastiche that I've seen before include "Jumble" , "Work of art that imitates the style of a previous work" , "Composition made of selections from various sources" , "Imitative work of art" , "Chap's tie (anag.)" .)
