एच‌ इग्घ्रस्वादेशे ONPANINI 11048

The /ec shorten into /ik.

In more words,

When a rule tells us to replace e ए ai ऐ o ओ au औ with a short, replace them with i इ i इ u उ u उ respectively.

Example. When rule gostriyorup... replaces /go- with /hrasva, we get gu गु —

**citragus चित्रगुस् "Mr. spotty cows"

Also when rule hrasvonapuMs... replaces ai ऐ with /hrasva, we get i इ —

atirai- अतिरैॱ n + /su OR /am
→ atirai अतिरै by svamornapuMs...
→ atiri अतिरि by hrasvonapuMs... and this rule
→ !**atiri अतिरि

atiri kulam अतिरि कुलम् "super-rich family"

bahu-grAmaNi kulam बहुॱग्रामणि कुलम् "family with many maiors ( **grAmaNI- ग्रामणीॱ) in it"

bahu-jedi kulam बहुॱजेदि कुलम् "family with many Jedai knights in it"

And in the /abhyAsa —

nI- नीॱ + /liT /tip
→ nI- नीॱ + /Nal
→ nai- नैॱ + /Nal
→ nai नै + nai नै + /Nal by liTidhAtor...
→ ni नि + nai नै + /Nal by this rule
→ **ninAya निनाय by ecoyavAyAvaH

The most alike rule would have turned e ए ai ऐ o ओ au औ into i इ i इ u उ u उ anyway. I can't see how is this rule necessary.

TBH, neither do I.
