Dhātūhi ṇe-ṇaya-ṇāpe-ṇāpayā kāritāni hetvatthe

1. Yo koci karoti, taṃ añño “karohi karohi” icc evaṃ bravīti, atha vā karontaṃ payojayati = kāreti, kārayati, kārāpeti, kārāpayati (someone does, another says thus to him, “do, do”, or engages him in doing: [he] causes him to do).
2. Ye keci karonti, te aññe “karotha karotha” icc evaṃ bruvanti = kārenti, kārayanti, kārāpenti, kārāpayanti (some people do, others say thus to them, “do, do”: [they] cause them to do).
3. Yo koci pacati, taṃ añño “pacāhi pacāhi” icc evaṃ bravīti, atha vā pacantaṃ payojayati = pāceti, pācayati, pācāpeti, pācāpayati (someone cooks, another says thus to him, “cook, cook”, or engages him in cooking: [he] causes him to cook).
4. Ye keci pacanti, te aññe “pacatha pacatha” icc evaṃ bruvanti = pācenti, pācayanti, pācāpenti, pācāpayanti (some people cook, others say thus to them, “cook, cook”: [they] cause them to cook).

Likewise:

1. Bhaṇeti, bhaṇayati, bhaṇāpeti, bhaṇāpayati ([he] causes to recite); bhaṇenti, bhaṇayanti, bhaṇāpenti, bhaṇāpayanti ([they] cause to recite).

In this way also others should be formed.

What is the purpose of saying “hetvatthe” (in the meaning of cause)? To prevent the operation of this rule when there is not the meaning of cause such as in the following examples: karoti ([he] does), pacati ([he] cooks).

By taking “attha”, there is also the suffix ‘ala’: jotalati ([he] causes to shine).
