ro ri रो रि ONPANINI 83014

Delete r र् before r र्.

There ain't such a thing as rr र्र् in Sanskrit. When two r र् come together, the first one disappears by this rule,

iSTais इष्टैस् + rUpavAn रूपवान्
→ iSTai इष्टै + /ru + rUpavAn रूपवान् by sasajuSoruH
→ !**iSTairUpavAn इष्टैरूपवान् by this rule

**zucIs शुचीस् + **rakSati रक्षति
→ zucI शुची + /ru + rakSati रक्षति by this rule
→ !**zucIrakSati शुचीरक्षति "the clean one protects"

and then maybe DhralopepUrv... kicks in —

**zucis शुचिस् + **rakSati रक्षति
→ zuci शुचि + /ru + rakSati रक्षति by this rule
→ zucIrakSati शुचीरक्षति by DhralopepUrv...
→ !**zucIrakSati' शुचीरक्षतिऽ "the clean one protects"

This rule can be a bit confusing because the erasing of r र् and lengthening of i इ sometimes sounds like another word that actually ends in I ई —

**zucI शुची + **rakSati रक्षति → !**zucIrakSati'' शुचीरक्षतिऽऽ by no rules

All your examples have /ru, will true r too be affected?

It will-

**punar पुनर् + **rakSati रक्षति
→ puna पुन + rakSati रक्षति by this rule
→ punA पुना + rakSati रक्षति by DhralopepUrv...
→ !**punArakSati पुनारक्षति "protects again"

Why doesn't this rule affect as अस्?

Because rule hazica erases the r र् before this rule can work —

azvas अश्वस् + dravati द्रवति
→ azva अश्व + /ru + dravati द्रवति by hazica
→ azva अश्व + u उ + dravati द्रवति
→ azv अश्व् + o ओ + dravati द्रवति
→ **azvodravati अश्वोद्रवति

How do you know hazica is stronger than this rule?

Rule hazica is not /asiddha, and this rule is.
