masc nom sg of paṭipucchitabba (ptp)
Analysis. paṭi + pucchita + bba: paṭi (back, in return, counter to) + pucchita (past participle of pucchati, to ask) + bba (gerundive suffix, expressing obligation or fitness). The prefix paṭi gives the sense of being asked back or questioned in return; the gerundive bba marks what ought to be done. Often appears in the Suttas to describe questions worthy of being asked or that merit a response.
Etymology. √pucch (to ask, question) is cognate with Sanskrit pṛcchati (asks) from PIE *prek- (to ask, request); this root also appears in Latin precor (I pray, beseech). The gerundive formation -bba (from *-tvya) parallels Sanskrit -tavya and shows the ancient obligation sense: what must be done.
