Original model given misshapen, creepy hat (9)
I believe the answer is:
archetype
'original model' is the definition.
(I've seen this before)
'misshapen creepy hat' is the wordplay.
'misshapen' indicates anagramming the letters.
'creepy'+'hat'='creepyhat'
'creepyhat' with letters rearranged gives 'ARCHETYPE'.
'given' is the link.
(Other definitions for archetype that I've seen before include "Model - perfect specimen" , "Perfect example" , "exemplary item)" , "Standard - cheap tyre (anag)" , "Very characteristic example" .)
