To aim it in carelessly could be a parody (9)
I believe the answer is:
imitation
'a parody' is the definition.
(thesaurus)
'to aim it in carelessly' is the wordplay.
'carelessly' indicates an anagram.
'to'+'aim'+'it'+'in'='toaimitin'
'toaimitin' anagrammed gives 'IMITATION'.
'could be' acts as a link.
(Other definitions for imitation that I've seen before include "Act of copying" , "produced by copyist?" , "Bogus" , "it's not for real" , "take-off" .)
