Now aim parting shot (6)
I believe the answer is:
trendy
'now' is the definition.
(I've seen this before)
'aim parting shot' is the wordplay.
'aim' becomes 'end' (both can mean a goal or purpose).
'parting' is an insertion indicator (inserted letters split or part another word).
'shot' becomes 'try' (both can mean an attempt).
'end' placed into 'try' is 'TRENDY'.
(Other definitions for trendy that I've seen before include "all the rage" , "following latest convention" , "In fashion, of popular style" , "following fashion" , "Chic (colloq.)" .)
