He makes many wicked (5)
I believe the answer is:
devil
'he' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'many wicked' is the wordplay.
'many' becomes 'd'.
'wicked' becomes 'evil' (similar in meaning).
'd'+'evil'='DEVIL'
'makes' is the link.
Can you help me to learn more?
(Other definitions for devil that I've seen before include "Lived with Satan" , "Evil supernatural being" , "Powerful evil spirit" , "Terror" , "Old Nick, Satan" .)
