Call someone mean, perhaps? (4)
I believe the answer is:
name
'call' is the definition.
(as in calling or naming someone something)
'someone mean perhaps?' is the wordplay.
'mean' can be anagrammed to 'NAME'.
Though, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for name that I've seen before include "Monicker" , "Appoint - famous person" , "Handle" , "Title, term" , "Title; famous person" .)
