पथिॱमथ्यृभुक्षामात् ONPANINI 71085

Replace /pathin- mathin- मथिन् RbhukSin- ऋभुक्षिन् with A आ before /su.

**pathin- पथिन् m + /su
→ pathan- पथन् + /su by itotsarvan... >
→ panthan- पन्थन् + /su by thonthaH >>
→ pantha- पन्थॱ + A आ + /su by this rule
→ panthA- पन्थाॱ + /su by akassavarN...
→ !**panthAs पन्थास्

When the /su is the /sambuddhi we still get he panthAH हे पन्थाः "hey road!". Finding out what rules form that is left as an exercise for the diligent student.

Shoudn't this sUtra be pathin;mathin;RbhukSiNAm At पथिन्मथिनृभुक्षिणामात्?

The general rule nalopaHprAt... says that the n न् in pathin पथिन् mathin मथिन् must go. Sometimes, /pANini irrgularly retains this sort of n न् for clarity, as he does in inhanpUSAry.... He might have done the same here with no change of meaning, but didn't do it.

Rule bhasyaTerlop... >>> forces the deletion of the in इन् of RbhukSin ऋभुक्षिन् before /Am. Leaving the in इन् in in this sUtra, like RbhukSiNAm ऋभुक्षिणाम्, would have made the bhasyaTerlop... >>> deletion optional by /jJApaka, which was undesired.
