sa;sajuSo ruH

सॱसजुषो रुः ONPANINI 82066

Replace all padafinal s स् with /ru.

What is this /ru thing?

It is just a letter r with an u label attached to it.

Most of the time /ru behaves just like a normal r — the u label is merely ignored —

**gurus + **apazyat
→ guru + /ru + apazyat
→ guru + r + apazyat
→ gururapazyat

**gurus + pause
→ guru + /ru + pause by this rule
→ guruH because /ru is r and kharavasAn... affects all r

So, what is this u label good for?

The r that has u label triggers certain rules, like hazica, atororapl... and bhobhagoagh... —

**azvas + **atra
→ azva + /ru + atra by this rule
→ **azvotra (by atororapl... and other rules)

**azvas + **dravati
→ azva + /ru + **dravati by this rule
→ !**azvodravati (by hazica)

**devAs + **Ucus → **devAUcus by bhobhagoagh... ff

Those rules will not be triggered by a true r (that is, by a normal r that has no u label) —

That hazica is not triggered by a true r —

**punar + **dravati → **punardravati JBJ

**punar + atra → !**punaratra JBJ

**punar + **Ucus → punarUcuH JBJ

What is that sajuS word doing in the sUtra?

Vedic rule. Do not pay attention to the man behind the curtain. But I must confess taht I cheated above. The FULL translation of the sUtra is —

Replace all padafinal s , and the vedic word sajuS , with /ru.

This tells the student that if the veda sings sajur devebhiH , that is not a mistake.

What does sajur devebhiH mean?

It means devais saha "with the gods".
