The ā before the affix mat has the acute accent, when the word is a name in the Feminine Gender.,
Thus अदुम्बरा꣡वती, पुष्करा꣡वती, शरा꣡वती 4.2.85. The lengthening takes place by 6.3.120. वीरणा꣡वती ॥ Why do we say 'the आ'? Observe इक्षुम꣡ती, द्रुमवती꣡ ॥ The words इक्षु Un. III. 157 and द्रुम 5.2.108 are end-acute, so accent is on मतुप् by (VI. I. I76). Why do we say when a name? Observe ख꣡ट्वावती ॥ खट्वा is formed by क्वन् and has acute on the first (Un. I. 151). Why do we say in the Feminine Gender? Observe शरावान् ॥ Why do we say when followed by मत् ? Observe गवादिनी ॥,
