'castigate' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?

'about terrible evil' is the wordplay.
'about' becomes 're' (common abbreviation for 'with reference to').
'terrible' indicates anagramming the letters.
'evil' with letters rearranged gives 'vile'.
're'+'vile'='REVILE'
