The Devil calls familiar appellations (9)
I believe the answer is:
nicknames
'familiar appellations' is the definition.
'nicknames' can be an answer for 'appellations' (nickname is a kind of appellation). I am unsure of the 'familiar' bit.
'the devil calls' is the wordplay.
'the devil' becomes 'nick' (Nick and Old Nick are names for the Devil).
'calls' becomes 'names' ('name' can be a synonym of 'call').
'nick'+'names'='NICKNAMES'
Can you help me to learn more?
(Other definitions for nicknames that I've seen before include "Chalky and Shorty, for instance" , "Handles" , "Familiar or affectionate add-on appellations" , "sobriquets" , "Monikers" .)
