See the end of Harry Potter prepared for printing plate (10)
I believe the answer is:
stereotype
'printing plate' is the definition.
(thesaurus)
'see the end of harry potter prepared' is the wordplay.
'the end of' says to take the final letters.
'prepared' indicates anagramming the letters.
The final letter of 'harry' is 'y'.
'see'+'y'+'potter'='seeypotter'
'seeypotter' with letters rearranged gives 'STEREOTYPE'.
'for' is the link.
(Other definitions for stereotype that I've seen before include "Conventional image" , "Sort of plate" , "Image to which people are expected to conform" , "cast" , "Set form" .)
