Upaccati
Upaccati,(?) in phrase “akkhīni upacciṁsu” at J.VI,187 is probably faulty for apaciyiṁsu aor.of apaciyyati,Pass.of apacināti (cp.upaciyyati › upacināti) “the eyes failed”,lost power,went bad; cp.apacaya falling off,diminution.If not this reading we should suggest upacchijjiṁsu from upacchindati “were destroyed”,which however is not quite the sense wanted.(Page 140)
