[On] *kupvoḥ* (Pā. Sū. 8.3.37): In the rule, the *visarga* occurs because it is followed by a *khar*, since *jihvāmūlīya* is included in *khar*. There is elision of the *visarga* by *kharpare śari*, since *jihvāmūlīya* is included in *śar*. Or the *visarga* alone remains by *vā śari* (Pā. Sū. 8.3.36). The letters *k* and *p* in the two substitutes are for the sake of pronunciation.
On "and the *visarga* from the word *ca*": As for what was said by the older grammarian, namely that an option is obtained from the word *ca*, that is incorrect; for, when released from [being substituted by] the *jihvāmūlīya* and *upadhmānīya*, the *visarga* would undesirably be replaced by *s*.
[On] *kānāmreḍite* (Pā. Sū. 8.3.12): When *kān kān* could simply have been said, the mention of *āmreḍita* is made so that it applies only where there is reduplication (*dvirukti*), and not here: *kān kān paśyasi* ("whom [and] whom do you see?"). Here, one word *kim* is used in inquiry, and the second in contempt. The meaning is: "Whom—what contemptible persons—do you see?"
On "kaskādiṣu ca" (Pā. Sū. 8.3.48): Here, the older grammarian said, "jihvāmūlīya and upadhmanīya do not replace the visarga." That is not the meaning of the sūtra, because "ka pau" are not marked with svarita, and "nañ" is not in the context. Rather, intimating that that [statement] is an explanation of the implied meaning, he says: "ka payor iti". In "kautaskutaḥ": in the sense of "come from somewhere or other" (kutaḥ kutaḥ āgataḥ), when tyap would apply after an indeclinable, an is used by virtue of the listing in the gaṇa. In "sarpiṣkuṇḍikā": although established simply by "nityaṃ samāse" (Pā. Sū. 8.3.45), the purpose of listing it here will be explained right there. On "senāsurā—": for if there were the augment tuk for cha, then upon cha undergoing devoicing there would be two ca-sounds. But if devoicing does not apply on account of the metarule regarding mutual contact (sannipātaparibhāṣā), a c-sound would be heard above the ch-sound—such is the sense.
