Steal celebrities' pseudonyms (9)
I believe the answer is:
nicknames
'pseudonyms' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'steal celebrities'' is the wordplay.
'steal' becomes 'nick' (nick can informally mean to steal).
'celebrities'' becomes 'names' (as in a phrase like 'a big name in fashion').
'nick'+'names'='NICKNAMES'
Can you help me to learn more?
(Other definitions for nicknames that I've seen before include "Handles" , "Monikers" , "Familiar or affectionate add-on appellations" , "Chalky and Shorty, for instance" , "sobriquets" .)
