प्रबलरुदितोच्छूननेत्रम्
प्रबल · रुदित · उच्छून · नेत्र
प्रबलं रुदितम्
कर्मधारय — hard weeping
प्रबलरुदितेन उच्छूने
तत्पुरुष (instrumental) — swollen by it
उच्छूने नेत्रे यस्य तत्
बहुव्रीहि — of which the two eyes are swollen
बहुव्रीहि — it refers to मुखम्. with its eyes swollen from hard weeping — Mallinātha gives the vigraha in one line and then spends more grammar on one member of it than on any word in the canto. **उच्छून is derived letter by letter.** It is क्त on √श्वि, to swell, in the active sense rather than the passive; the त् of the affix becomes न् because the root is ओदित्, marked with an ओ in the Dhātupāṭha, by Pāṇini 8.2.45 ओदितश्च; the व् of श्वि becomes the vowel उ by 6.1.15 वचिस्वपियजादीनां किति, since क्त is कित्; that उ and the इ after it become one उ by 6.1.108 सम्प्रसारणाच्च; and the उ lengthens to ऊ after a consonant by 6.4.2 हलः. शून, and with उद् in front, उच्छून. **Then he rejects somebody else's derivation of the same form.** A rule exists that would give it in one step — 6.4.19 च्छ्वोः शूडनुनासिके च, which substitutes ऊठ् for a व् before a nasal-initial affix — and he calls the derivation that uses it प्रामादिकी, careless, and उपेक्ष्या, to be set aside, for two reasons: that the root's इ would then be left with nothing to remove it, and that the substitution is qualified by the last letter. And he closes on what the swelling means rather than how it is spelled: एतेन विषादो व्यज्यते, by this dejection is suggested
uncheckedMallinātha, Sañjīvinī, who unpacks प्रबलरुदितेनोच्छूने उच्छ्वसिते नेत्रे यस्य तत् and derives उच्छून with four sūtras, then rejects a derivation by 6.4.19 as प्रामादिकी; Pāṇini 8.2.45, 6.1.15, 6.1.108, 6.4.2 and 6.4.19 by way of skt-mcp for the sūtras' text. `vendor/meghaduta-sanjivini.itx` gives the rejected derivation's source as `vartamAnasAmIpyaprakriyA`, which the run cannot resolve into a title or a name, and prints `antyasena` in his second reason, where the sense wants the instrumental of अन्त्य; only what is legible is read“ucchūneti śvayateḥ kartari ktaḥ || “oditaś ca” iti niṣṭhānatvam | “vacisvapi—” ityādinā samprasāraṇam | “samprasāraṇāc ca” iti pūrvarūpatvam | “halaḥ” iti dīrghaḥ || “cchvoḥ śūḍanunāsike ca” ity ūṭhādeśe kṛte rūpasiddhir iti … prāmādikīty upekṣyā … etena viṣādo vyajyate”
