One to trick revered person (4)
I believe the answer is:
icon
'revered person' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'one to trick' is the wordplay.
'one' becomes 'I' (Roman numeral).
'to trick' becomes 'con' (a con is a fraud or trick).
'i'+'con'='ICON'
Can you help me to learn more?
(Other definitions for icon that I've seen before include "Image; celebrity" , "Religious (or computing) picture" , "Someone uncritically admired" , "hero!" , "Representative figure as on computer screen" .)
