Ntuss’ anto yosu ca

1. Guṇavantesu = guṇavantu + su (‘u’ of ‘ntu’ becomes ‘a’ (§92); ‘a’ becomes ‘e’ (§89)).
2. The formation of the rest of the examples is similar to the previous one.

What is the purpose of saying “of ‘ntu’”? [This sutta does not apply when there is no ‘ntu’, such as in] isīnaṃ.

What is the purpose of saying “when these follow”? [This sutta does not apply when ‘su’, ‘naṃ’, ‘hi’ and ‘yo’ do not follow, such as in] guṇavā.

By taking “ca”, when other inflections follow, there is also ‘a’. Examples: guṇavantasmiṃ, guṇavantena.

By taking “anta”, the end vowel of the suffix ‘ntu’ becomes ‘a’, and ‘yo’ becomes ‘i’. Example:

1. Guṇavanti = guṇavantu + yo (‘u’ of ‘ntu’ becomes ‘a’ by “anta” (§92); ‘yo’ becomes ‘i’ (§92); ‘a’ is elided (§83)).
