130. Combination requiring notice

As regards the accent—here, as in the preceding case (128), the only combination requiring notice is that of an acute i- or u- vowel with a following grave: the result is circumflex; and such cases of circumflex are many times more frequent than any and all others. Examples are:

व्यु॑ष्ति vyùṣṭi (ví-uṣṭi); अभ्य॑र्चति abhyàrcati;

नद्यौ॑ nadyāù (nadí-āu);

स्वि॑ष्ट svìṣṭa (sú-iṣṭa); तन्व॑स् tanvàs (tanū́-as).

a. Of a similar combination of acute ṛ́ with following grave, only a single case has been noted in accented texts: namely, vijñātr ètát (i.e. vijñātṛ́ etát: ÇB. xiv. 6. 811); the accentuation is in accordance with the rules for i and u.
