ay is substituted for the i of ṇi before the Absolutive affix lyap when the vowel preceding the i is light.,
Thus प्रशमय्य गतः, संदमय्य गतः, प्रवेभिदय्य, प्रगणय्य ॥ But प्रपात्य गतः the vowel preceding the इ being long. Here 6.4.51 applies. The shortening, the elision of य and the elision of अ should not be considered as asiddha, as their place of operation is not the same. Thus शम् + णिच् = शामि; this आ is shortened by 6.4.92, and we have शमि ॥ This shortening is not to be considered as asiddha, for if asiddha, there being no laghu purva, the present rule would not apply. Similarly वेभिद्य is the Intensive root, its य is elided by 6.4.49, this elision is not considered as asiddha, if it were asiddha, the इ of भि would not be laghu. Similarly the elision of अ in गण which is a root which ends in अ, (see Dhatupatha Churadi 309), is not considered as asiddha for similar reasons.,
