Wicked name that is for villain (6)
I believe the answer is:
meanie
'villain' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'wicked name that is' is the wordplay.
'wicked' indicates an anagram.
'that is' becomes 'i.e.' (synonyms).
'name' anagrammed gives 'mean'.
'mean'+'ie'='MEANIE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for meanie that I've seen before include "Stingy person (informal)" , "nasty type" , "nasty person" , "Ungenerous person" , "Selfish type (informal)" .)
