Paltry matter (6)
I believe the answer is:
trifle
'paltry matter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trifle that I've seen before include "Party dessert" , "Mess" , "Insignificant item - dessert" , "Play - trivia" , "Filter (anag.)" .)
