Commentary
In the छन्दस् (Vedas) 1. दुरस्यु 2. द्रविणस्यु 3. वृषण्यति and 4. रिषण्यति are irregularly formed
As अवियोना दुरस्युः, (= दुष्टीयति with the affix क्यच् added to दुष्ट), द्रविणस्यु र्विपन्यया (द्रविणीयति, here द्रविणस् is substituted for द्रविण similarly). वृषण्यति = वृषीयति (वृषण् substituted for वृष) ॥ रिषण्यति = रिष्टीयति (रिषण् substituted for रिष्ट) ॥
