Commentary
When लिट् (Perfect Tense) follows, वयि is optionally the substitute follows of वेञ् 'to weave'.
In the Perfect tense thus we have two roots: Let us first take वेञ्. Then we have regulary वे + लिट् = वे + णल् = ववौ. The roots in ए, ऐ and ओ are treated like roots ending in आ thus :-
- 3rd person - ववौ, ववतुः, ववुः
- 2nd person - वविथ or ववाथ, ववथुः, वव
- 1st person - ववौ, वविव, वविम
In this case samprasarana ordained by 6.1.17 does not take place by 6.1.40
When however we take the base वय्, th इ being for the sake of articulation only, we have the following forms:- वय् + णल् = वय् + वय् + अ 6.1.8 = उय् + वय् + अ 6.1.17 = उवाय; the य is not changed into इ by 6.1.38. In this dual we have वय् + अतुस् = उय् + अतुः 6.1.15 = उ + उय् + अतुः 7.4.60 = ऊयतुः The affix अतुस् being कित् affix by rule 1.2.5 there is samprasarana before reduplication. Thus we have उयाय, ऊयतुः, ऊयुः. Further by rule 6.1.39 before कित् affixes व may be optionally substituted for य, i. e., ऊयतुः or ऊवतुः and ऊयुः or ऊवुः
