Satirist, a Bel Air comic, on second (8)
I believe the answer is:
rabelais
'satirist' is the definition.
(Rabelais is an example)
'a bel air comic on second' is the wordplay.
'comic' indicates an anagram.
'on' is an insertion indicator (as in clothing \'on\' a person).
'second' becomes 's' (common abbreviation**).
'air' is an anagram of 'rai'.
'a'+'bel'='abel'
'abel' inserted inside 'rai' is 'rabelai'.
'rabelai'+'s'='RABELAIS'
(Other definitions for rabelais that I've seen before include "Sixteenth century French satirical author" , "Racy writer" , "Sixteenth century French author of Gargantua and Pantagruel" , "teller of stories" , "bawdy writer" .)
