Awful liar imprisoned by revolutionary prince (7)
I believe the answer is:
charlie
'prince' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'awful liar imprisoned by revolutionary' is the wordplay.
'awful' indicates an anagram.
'imprisoned by' is an insertion indicator.
'revolutionary' becomes 'Che' (Che Guevara the Marxist revolutionary).
'liar' anagrammed gives 'arli'.
'arli' going inside 'che' is 'CHARLIE'.
Can you help me to learn more?
(Other definitions for charlie that I've seen before include "Cocaine (colloq.), fool (colloq.)" , "Fool; man's name" , "Fool - drug (slang)" , "Chaplinesque man" , "Silly person" .)
