Unfortunately Aaron did live with con artist (8,2,5)
I believe the answer is:
leonardo da vinci
'artist' is the definition.
(Leonardo da Vinci is an example)
'unfortunately aaron did live with con' is the wordplay.
'unfortunately' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'aaron'+'did'+'live'='aarondidlive'
'aarondidlive' after 'con' is 'conaarondidlive'.
'conaarondidlive' anagrammed gives 'LEONARDO DA VINCI'.
(Other definitions for leonardo da vinci that I've seen before include "He painted" , "Renowned painter" , "Italian painter" , "artist ..." , "famous Italian" .)
