Analysis. du- (bad, hard) + viññāpaya (instructable, from viññāpeti 'to teach, make known'). Lit. 'badly teachable' or 'hard to make known'.
Etymology. du- (bad, hard, gone wrong; cognate with Greek dys-) combined with the verbal adjective viññāpaya (from viññāpeti, itself vi- 'apart, clearly' + ñāpeti 'causes to know', from √ñā 'to know'). The prefix du- renders the quality negative or difficult, much as English 'mis-' or 'un-' intensifies hardship.
