Commentary
In the Nominative 1st-Case plural यूय is substituted for युष्म् and वय for अस्म्।
As यूयम्, वयम्, परमयूयम्, परमवयम्, अतियूयम, अतिवयम् ॥ The Tadanta-vidhi applies here. That rule applies in this angadhikara on the maxim अङ्गाधिकारे तस्य च तदुत्तरपदस्य च ॥ See also 7.3.10. In यूयम् and वयम्, the final द् is elided by 7.2.90, and we have यूय and वय + अ + अम् 7.1.28 = यूयम् and वयम् 6.1.97 and 6.1.107.
