Bit in Parsifal seems artificial (5)
I believe the answer is:
false
'artificial' is the definition.
(similar in meaning)
'bit in parsifal seems' is the wordplay.
'bit' says the answer is hidden in the clue (I've seen 'bit of' mean this).
'FALSE' is hidden within 'in parsifal seems'.
(Other definitions for false that I've seen before include "Misleading" , "Not in accordance with fact" , "Erroneous" , "Mendacious" , "Wrong" .)
