Free loader for trial? (6)
I believe the answer is:
ordeal
'for trial?' is the definition.
(I've seen this before)
'free loader' is the wordplay.
'free' indicates anagramming the letters.
'loader' with letters rearranged gives 'ORDEAL'.
(Other definitions for ordeal that I've seen before include "A difficult or harrowing time" , "Severe or trying experience" , "Severely trying experience" , "Trouble" , "trying affair" .)
