On "ambārthanadyorhrasvaḥ" (Pā. Sū. 7.3.107): Here there is a vārttika: "māturmātacputrārthamarhate". The substitute mātac occurs in place of the word mātṛ in the vocative singular when the praiseworthiness of the son by the mother is to be conveyed: [as in] "she whose mother is Gārgī is gārgīmātṛkaḥ; the address to him is he gārgīmāta". This is an exception to the compound-final suffix [kap] prescribed by "nadyṛtaśca" (Pā. Sū. 5.4.153). But where praiseworthiness is not to be conveyed, but merely the statement of the actual state of affairs, there only kap occurs: gārgīmātṛka.
On "the base which ends in āp": As for what was said by those explaining the rule "yāḍāpaḥ"—that in atikhaṭvāya there is no yāṭ because it is derivative, and likewise in atisarvāya there is no syāṭ—that is rash; for the metarule of primary over derivative does not operate in the domain of extended application, because that would entail the uselessness of the extended application. Therefore, yāṭ is unavoidable. But for syāṭ there is no occasion at all, because of the exclusion of technical names and secondary members from the list [of pronouns]. On "kecittu": the authors of the Pariśiṣṭa and others.
On "ṅiti hrasvaśca" (Pā. Sū. 1.4.6): This is an option where [the designation nadī] was not applicable. For it is commenced when there is non-application in the case of the two short vowels, whereas in the case of the other two [long vowels] the prohibition "neyaṅuvaṅsthānāvakāvarṇau" (Pā. Sū. 1.4.4) had presented itself. Here, "having iyan and uvaṅ as substitutes", "other than the word strī", and "invariably feminine" are three qualifiers of long ī and long ū; but for the two short vowels, there is only the qualifier "in the feminine", and not extending to being invariably feminine. Otherwise, words such as iṣu and aśani, which have two genders, and words of all genders, would not have the technical name nadī even when feminine, because according to Kaiyaṭa’s method they lack invariable femininity, and also because according to Haradatta’s view, there is nothing to be excluded by the mention of "nitya" in the portion dealing with short vowels. For this very reason, setting aside the mention of ākhyā, the word strī alone is extracted and connected; this is what he means by: "and the short vowels i and u in the feminine".
On "when the substitution of aut has presented itself": The purport is: because it is subsequent. As for the fact that the older grammarian explained under the rule "aut" (Pā. Sū. 7.3.118) as "after those devoid of the technical names ghi and nadī", that is not the literal meaning of the words, but is obtained from the two rules preceding and following. And thus, the failure of the older grammarian to cite the rule "idudbhyām" (Pā. Sū. 7.3.117) is entirely an oversight.
