In denoting a feminine name, the tadrājā is elided after the words 1. avanti 2. kunti and 3. kuru ,
That is to say the affix 'nyan'. 4.1.171 after the word 'Avanti' and 'Kunti', and the affix 'nya' after the word 'Kuru' are elided when the word to be formed is the name of a female. Thus अवन्ती, कुन्ती and कुरु 'a daughter or princess of Avanti, Kunti of Kuru'. The word कुरु takes ऊङ् in the feminine by 4.1.66. Why do we say 'in denoting the feminine'? Observe आवन्त्यः, कौरव्यः and कौन्त्यः ॥,
