Categorise Harry Potter's eye (10)
I believe the answer is:
stereotype
'categorise' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps they are linked in a way I don't understand?
'harry potter's eye' is the wordplay.
'harry' is an anagram indicator (harry can mean to attack or spoil).
'potters'+'eye'='potterseye'
'potterseye' is an anagram of 'STEREOTYPE'.
Can you help me to learn more?
(Other definitions for stereotype that I've seen before include "Pigeonhole" , "Conventional image" , "Spring back (in fear)" , "Fixed conventionalised image" , "received idea?" .)
