And the feminine ṅīṣ comes optionally after compounds ending with 1. nāsikā 'a nose' 2. udara 'belly' 3. oṣṭha 'lip' 4. jaṃghā 'leg' 5. danta 'tooth' 6. karṇa 'ear' and 7. śṛṅga 'horn'.,
This is an exception to the last and the succeeding sutra. Some of the words above given are either such which have a conjunct penultimate letter, and thus beyond the scope of 4.1.54; or they are polysyllabic words and thus covered by 4.1.56. Though this rule is an exception to 4.1.54 and 4.1.56; yet it is qualified by (IV. I. 57). Thus तुङ्गनासिका or तुङ्गनासिकी, तिलोदरी or तिलोदरा, बिम्बोष्ठी or बिम्बोष्ठा, दीर्घजंघी or दीर्घजंघा, समदन्ती or समदन्ता, चारुकर्णी or चारुकर्णा, तीक्ष्णसृङ्गी or तीक्ष्णशृङ्गा ॥
Vart:- So also after the word पुच्छ 'tail'. As कल्याणपुच्छा or कल्याणपुच्छी ॥
Vart:- The affix nish comes necessarily and not optionally after compounds of पुच्छ with कबर, मणि, विष and शर ॥ As, कबरपुच्छी 'a peahen' मणिपुच्छी, विषपुच्छी, 'a scorpion' and शरपुच्छी ॥
Vart:- So also the feminine affix nish is necessarily employed after the words पक्ष and पुच्छ when used as a simile or as objects of comparison. As उलूकपक्षी सेना, उलूकपुच्छी शाला ॥,
