The affix ṇya comes in the sense of descendant after the words kuru etc.,
Thus कुरु + ण्य = कौरव्यः ॥ So also गार्ग्यः ॥ The word कुरु takes the affix ण्य by 4.1.172, so that the form कौरव्यः is evolved both under the present sutra and sutra 4.1.172; but the difference in these two words is this. The word कौरव्य formed by the ण्य of 4.1.172, loses its affix in the plural, because ण्य of 4.1.172 is a Tadraja affix (see (II 4. 62): but the word कौरव्य formed by the present sutra retains its affix in the plural. As कौरव्यः ॥ The word कौरव्य occurs in the Tikadi class 4.1.154, and it takes as such the affix फिञ्. As कौरव्यायणिः ॥
The word रथकार occurs in this class and it means the caste known as Rathakara. Rathakara is a caste a little lower than the twice-born. See Yajnyavalkya Smriti, V. 95. But when the word रथकार means a person who makes chariots, that is an artisan, it will take the affix ण्य not by this Sutra, but by the succeeding sutra.
The word केशिनी occurs in this class. Its derivative will be कैशिन्यः ॥ There will not be punvadbhava as required by 6.3.34 &c. For had there been punvadbhava, then by भस्यढे तद्धिते, all Bha bases will become punvad before a taddhita affix except ढ ॥ Therefore केशिनी + ण्य = केशिन् + ण्य ॥ At this stage rule 6.1.144 will appear and cause the elision of टि and we shall have केश् + ण्य = कैश्य ॥ But this is not the form desired, hence the word केशिनी is read with the feminine affix in the list.
The word वेन takes this affix in the Vedic literature. Therefore, the form वैन्य in the modern Sanskrit is incorrect.
The word वामरथ occurs in this class. With the exception of accent, it is treated in every other respect like a word of Kanvadi class, a subdivision of Gargadi 4.4.105. Thus disciples of वामरथ्यः will be formed by the affix अण् 4.2.111. As वामरथ्य + अण् = वामरथः 6.1.105. The plural will be वामरथाः 2.4.64. The feminine gender will be वामरथी 4.1.16 or वामरथ्यायनी 4.1.17. The Yuvan will be वामरथ्यायनः 4.1.101. So also it will take अण् when the sense of collection &c is expressed 4.3.127: as वामरथानि ॥ But as to accent, it will not be like Kanvadi words, for while those words being formed by the affix यञ् will have udatta on the first syllable 6.1.197 the accent of वामरथ्य will be governed by ण्य ॥
