Replace R ऋ RR ॠ L ऌ (of an /abhyAsa) with a अ.

Examples:

vRdh वृध् + /liT /ta
→ vR वृ + vRdh वृध् + /ez by liTidhAtor...
→ va व + vRdh वृध् + ez एश् by this rule
→ !**vavRdhe ववृधे "grew"

tRR तॄ + /liT /tip
→ tRR तॄ + /Nal
→ tar तर् + /Nal by RcchatyRRtAm
→ tAr तार् + /Nal by ata::upadh...
→ tA ता +tAr तार् + /Nal by liTidhAtor...
→ ta त +tAr तार् + /Nal by <7 hrasvaH
→ !**tatAra ततार "he crossed"

(Writing that as

tRR तॄ + /liT /tip
→ tRR तॄ + /Nal
→ **tatar- ततर् + /Nal
→ **tatAra ततार "he crossed" by ata::upadh...

might be technically incorrect, but sort of works.)

tRR तॄ + /liT /jhi
→ tRR तॄ + /us
→ **tatar- ततर् + /us
→ ter तेर् + us उस् by ata::ekah...
→ !**terus तेरुस् "they crossed"

R ऋ + /atus
→ ar अर् + /atus by RcchatyRRtAm
→ a अ + ar अर् + /atus by liTidhAtor...
→ Ar आर् + /atus by ata::AdeH >>>>
→ **Aratus आरतुस्

tRR तॄ before /liT
→ tar तर् by RcchatyRRtAm
→ ta त + tar तर् by liTidhAtor... and ekAcodvepr...
→ !**tatar- ततर्

tRR तॄ + /liT /mas
→ tRR तॄ + /ma
→ tRR तॄ + ima इम by kRsRbhRvRst...
→ **tatar- ततर् + ima इम
→ !**terima तेरिम "we crossed" by ata::ekah...

Wait, doesn't uraNraparaH say that whenever a rule replaces R ऋ with a अ, we get ar अर्? How come we didn't get varvrdhe above?

TBH, we did get it. But I was sloppy in my derivation of **vavRdhe ववृधे. I should have written this —

vRdh वृध् + /liT /ta
→ vR वृ + vRdh वृध् + /ez by liTidhAtor...
→ va व + vRdh वृध् + ez एश् by this rule
→ var वर् + vRdh वृध् + ez एश् by uraNraparaH
→ va व + vRdh वृध् + ez एश् by <6 halAdizzeSaH
→ **vavRdhe ववृधे "grew"

This happens every single time we use this rule.

So, please note down that whenever I say "by urat उरत्", I actually mean "by urat उरत् and uraNraparaH and <6 halAdizzeSaH".
