१७८- अपृक्त एकाल् प्रत्ययः।178. apṛkta ekāl pratyayaḥ.एकश्चासौ अल् एकाल्।ekaścāsau al — ekāl (a single al).अपृक्तः प्रथमान्तम्, एकाल् प्रथमान्तं, प्रत्ययः प्रथमान्तं, त्रिपदमिदं सूत्रम्।apṛktaḥ is in the nominative case, ekāl is in the nominative case, pratyayaḥ is in the nominative case; this sūtra has three words.
एक अल् अल् रूप जो प्रत्यय वह अपृक्तसंज्ञक होता है अर्थात् उसकी अपृक्तसंज्ञा होती है।A suffix that consists of a single al receives the name apṛkta; that is, it receives the apṛkta-saṁjñā.
उदाहरणार्थ- सु प्रत्यय में स् तथा उ दो अल् थे किन्तु उकार की इत्संज्ञा और लोप हो जाने के कारण केवल स् बचा हुआ है।For example, in the suffix su there were two als, s and u; but because the ukāra received the it-saṁjñā and was elided, only s remains.इसलिए सु का सकार एक मात्र अल् है, अतः उसकी अपृक्तसंज्ञा हो गई।Therefore the sakāra of su is a single al, and so it received the apṛkta-saṁjñā.
