Father seen around at send-up (6)
I believe the answer is:
satire
'send-up' is the definition.
(I've seen this in another clue)
'father seen around at' is the wordplay.
'father' becomes 'sire' (synonyms).
'seen around' is an insertion indicator.
'sire' enclosing 'at' is 'SATIRE'.
(Other definitions for satire that I've seen before include "Work of ridicule" , "text of Juvenal" , "Use of irony in writing" , "Humorous criticism of folly or vice" , "burlesque" .)
