RRta:: id dhAtoH

ॠत‌ इद्धातोः ONPANINI 71100

Replace the RR ॠ of a root with i इ.

Of course uraNraparaH turns that i इ into ir इर्.

Examples —

hole in vistIrNA

vistr विस्त्र् "expand, spread out, diffuse" + /kta
→ vistRR विस्तॄ + /kta by !!
→ vistir विस्तिर् + /kta by this rule and uraNraparaH
→ vistIr विस्तीर् + /kta by halica
→ vistIr विस्तीर् + na न by radAbhyAnniSTh...
→ vistIr विस्तीर् + Na ण with /Natvam
→ !**vistIrNa- विस्तीर्णॱ "vast, wide, extended, big"

/sam + kRR कॄ + /kta
→ **saGkIrNa- सङ्कीर्णॱ "narrow"

And from kRR कॄ "scatter" —

kRR कॄ + /laT /tip
→ kRR कॄ + /za + /tip
→ !**kirati किरति by this rule and uraNraparaH

With /san —

kR कृ + /san
→ kRR कॄ + /san by ajjhanagam...
→ cikRR चिकॄ + /san
→ cikir चिकिर् + /san by this rule and uraNraparaH
→ cikir चिकिर् + /san by halica
→ **cikIrSa चिकीर्ष

Why do we say "of a root"?

To keep this rule from affecting —
