Regarding "of sound": regarding "of imitation": the meaning is, of a sound consisting of fully distinct speech sounds such as a. And its nature as an imitation is to be understood through some degree of resemblance. As for what the older grammarian said—"Why [specify] 'ending in a'? So that it does not apply to that which ends in d"; and what was explained, that "ending in d" is illustrative of other forms as well, such as vaṭak, marut, and so forth—that is baseless, because the question, and the answer "that which ends in d", lack any foundation. As for what [others] explained—the question is: Since the result is achieved by continuing ataḥ from "ato guṇe" (Pā. Sū. 6.1.97) and relying on the heading of words, [why specify at again]? And the answer is: Even when there is the state of ending in d due to jaśtva, it would apply; but because the explicit mention of at intends an audible t-ending, it does not—that is questionable; for, because the rule of jaśtva is suspended (asiddha), single substitute for preceding and following (pararūpa) alone applies; and also because it would entail that the counterexample paṭatpaṭaditi under the prohibition "nāmreḍitasya" (Pā. Sū. 6.1.99) would be irrelevant. For there, according to your statement, it would not obtain at all, because it ends in d. By this, that text also is refuted which states: "In paṭat iti there is no jaśtva because it is not an inflected word (pada), just like 'gavititi ayam āha', since there is an absence of case ending when intending non-difference between the imitated and the imitation"; because it contradicts subsequent texts, and because, jaśtva being suspended, it is blocked by pararūpa alone. If it is objected: But that too is obligatory, and so how could there be usage without pararūpa?—it is not so; for [the author] himself explained that this is an unworldly derivational sentence (alaukika-prakriyāvākya), and because that is possible when close junction (saṃhitā) is not intended: this is the direction.
