१७९- हल्ङ्याब्ध्यो दीर्घात्सुतिस्यपृक्तं हल्।179. halṅyābbhyo dīrghāt sutisyapṛktaṁ hal.हल् च ङीप् च आप् च तेषामितरेतरद्वन्द्वो हल्ङ्याबः, तेभ्यो हल्ङ्याभ्यः।hal and ṅīp and āp — of these there is an itaretara-dvandva compound halṅyāb; from these comes halṅyābbhyaḥ (ablative).सु श्च, तिश्च, सिश्च तेषां समाहारद्वन्द्वः, सुतिसि, सुतिसिनोऽपृक्तं सुतिस्यपृक्तम्।su, ti, and si — of these there is a samāhāra-dvandva compound, sutisi; the apṛkta of sutisi is sutisyapṛkta.हल्ङ्याब्ध्यः पञ्चम्यन्तं, दीर्घात् पञ्चम्यन्तं, सुतिस्यपृक्तं प्रथमान्तं, हल् प्रथमान्तम्, अनेकपदमिदं सूत्रम्।halṅyābbhyaḥ is in the ablative (pañcamī), dīrghāt is in the ablative, sutisyapṛktaṁ is in the nominative (prathamā), hal is in the nominative; this sūtra has several words.लोपो व्योर्वलि से लोपः की अनुवृत्ति आती है।The word lopaḥ is carried over (anuvṛtti) from ‘lopo vyor vali’.सुतिसिनो यत् अपृक्तं हल्, स लुप्यते।The apṛkta hal of su-ti-si is elided.
जिसके अन्त्य में हल् हो ऐसे हलन्त से परे तथा दीर्घ जो डी और आप् अन्त में हों ऐसे ड्यन्त एवं आबन्त शब्दों से परे सु-ति-सि का जो अपृक्तसंज्ञक हल्, उसका लोप होता है।After a word ending in a consonant (halanta, whose final is a hal), and after ṅyanta and ābanta words whose final long ī (from ṅī) and ā (from āp) stand at the end, the hal bearing the apṛkta-saṁjñā that belongs to su, ti, si is elided.
जिसका लोप होगा वह सु का सकार होगा या ति का तकार होगा या सि का सकार होगा किन्तु अपृक्त (एक अल्) हो तो और उसके पूर्व में हल् अक्षर हो या डी प्रत्यय के बाद बचा हुआ ईकार अथवा आप् (टाप्) प्रत्यय के बाद बचा हुआ आकार दीर्घ ही बने हुए हों तभी।That which is elided will be the sakāra of su, or the takāra of ti, or the sakāra of si — but only when it is apṛkta (a single al), and only when the letter preceding it is a consonant (hal), or when the īkāra remaining after the ṅī pratyaya or the ākāra remaining after the āp (ṭāp) pratyaya stand as long vowels.
