Caggahaṇena dhakārassa hakārādeso hoti. Sāhu dassanam ariyānaṃ (Khu. i, 34).

By taking “ca”, there is also substitution of ‘dha’ by ‘ha’, [such as in] “sāhu dassanam ariyānaṃ”.

Suttavibhāgena bahudhā siyā: To dassa, yathā? Sugato (Vin. i, 1). Ṭo tassa, yathā? Dukkaṭaṃ (Vin. v, 262). Dho tassa, yathā? Gandhabbo (M. i, 332). Tro ttassa, yathā? Atrajo (Vin. iii, 428). Ko gassa, yathā? Kulūpako (Vin. i, 192). Lo rassa, yathā? Mahāsālo (D. ii, 121). Jo yassa, yathā? Gavajo (Khu. v, 283). Bbo vvassa, yathā? Kubbato (Khu. v, 95). Ko yassa, yathā? Sake (Khu. vi, 325).

By dividing the sutta [into similar rules], there are many applications: ‘d’ is changed to ‘t’ as in “Sugato” (Sugado → Sugato); ‘t’ to ‘ṭ’ as in “dukkaṭaṃ” (dukkataṃ → dukkaṭaṃ); ‘t’ to ‘dh’ as in “gandhabbo” (gantabbo → gandhabbo); ‘tt’ to ‘tr’ as in “atrajo” (attajo → atrajo); ‘g’ to ‘k’ as in “kulūpako” (kulūpago → kulūpako); ‘r’ to ‘l’ as in “mahāsālo” (mahāsāro → mahāsālo); ‘y’ to ‘j’ as in “gavajo” (gavayo → gavajo); ‘vv’ to ‘bb’ as in “kubbato” (kuvvato → kubbato); ‘y’ to ‘k’ as in “sake” (saye → sake); ‘j’ to ‘y’ as in “niyaṃ” (nijaṃ → niyaṃ); ‘t’ to ‘k’ as in “niyako” (niyato → niyako); ‘tt’ to ‘cc’ as in “bhacco” (bhatto → bhacco); ‘p’ to ‘ph’ as in “nipphatti” (nippatti → nipphatti); ‘k’ to ‘kh’ as in “nikkhamati” (nikkamati → nikkhamati). Other examples beginning with these should be formed.
