After a aṅga (stem) ending in a or ā the affix as of the Nominative 1st-Case plural gets, in the chandas (Vedas), the augment as (asuk) at the end.,
Thus ब्राह्मणासः पितरः सोम्यासः for ब्राह्मणाः and सोम्याः ॥ Rig VI. 75. 10. ये पूर्वासो य उपरासः (Rig X. 15. 2) for पूर्वे and उपरे ॥ So also पुतासः (Rig I. 3. 4) Why is not, after the adding of the augment असुक्, the जस् changed to शी in the last example, as required by (VII. I. 17), and on the maxim पुनः प्रसङ्गः विज्ञानात्? No, the maxim that applies here is सकृद् गतौ विप्रतिषेधे यद्बाधितं, तद्बाधितमेव ॥
