Pseudo-enigma? (5)
I believe the answer is:
poser
I believe this is a double definition.
'pseudo' is the first definition.
(I know that poser is a type of pseudo)
'enigma?' is the second definition.
(I've seen this in another clue)
(Other definitions for poser that I've seen before include "Exhibitionist" , "Problem set by the model" , "Hard problem" , "Conundrum - model?" , "Baffling question or problem" .)
