Artie's madly mocking work (6)
I believe the answer is:
satire
'mocking work' is the definition.
'satire' can be an answer for 'work' (I've seen this before). I'm not certain of the 'mocking' bit.
'artie's madly' is the wordplay.
'madly' is an anagram indicator.
'arties' is an anagram of 'SATIRE'.
Can you help me to learn more?
(Other definitions for satire that I've seen before include "Lampoon(ery)" , "text of Juvenal" , "Irony and ridicule in speech or writing" , "Jonathan Swift's forte?" , "Biting humour exposing vice, folly etc." .)
