doubtful whether a legitimate form as upa + pad or a diaeretic form of uppajjati = ud + pad. In this case all passages ought to go under the latter. Trenckner however (Notes 77) defends upa˚ & considers in many cases upp˚ a substitution for upa. The diaeresis may be due to metre, as nearly all forms are found in poetry. The variant reading upp˚ is apparently frequent; but it is almost impossible to distinguish between upap˚ and upp˚ in the Sinhalese writing, and either the scribe or the reader may mistake one for the other
