zRR;dRR;prAM hrasvo vA

शॄॱदॄॱप्रां ह्रस्वो वा ONPANINI 74012

Shorten zRR शॄ dRR दॄ pRR पॄ optionally (before a /kit /liT).

This short R ऋ debars the /guNa from < RcchatyRRtAm.

As for instance, /atus is nearly always /kit, by asaMyogAll.... So we say —

pRR पॄ + /liT /tas
→ pa प + pRR पॄ + /atus
→ pa प + pR पृ + /atus by this rule
→ pa प + pr प्र् + /atus by ikoyaNaci
→ !**papratuH पप्रतुः "both protected"

ITA —

pRR पॄ + /liT /tas
→ **paparatus पपरतुस् "both protected" by < RcchatyRRtAm

What's with the word hrasvaH ? If the sUtra had been zRR;dRR;prAM vA , that would have prevented the guNa from < RcchatyRRtAm anyway, and ikoy would still turn pRR into pr , nvm if short of long.

You forget that udoSThyapUrv... would have made pipuratuH in that case.
