(The stem of a weak affix that starts with) y य् or a vowel is whimpy (/bha).

This debars the /padaness from < svAdiSvasarv....

Example. /Gas is weak and starts with a अ. So **rAjan- राजन् is whimpy before /Gas. Being whimpy makes rAjan राजन् lose its a अ —

**rAjan- राजन् + /Gas → **rAjJas राज्ञस्

However, /sup' starts with a consonant that is not y य्. So, **rAjan- राजन् is not whimpy before /sup'. As /sup' is not strong, **rAjan- राजन् is /pada by < svAdiSvasarv.... Being /pada makes it lose the n न् —

**rAjan- राजन् + /sup' → **rAjasu राजसु

Finally, before strong affixes, **rAjan- राजन् is neither whimpy nor /pada. So it keeps the a अ and the n न् —

**rAjan- राजन् + /sambuddhi → **rAjan' राजन्ऽ

**rAjan- राजन् + /au → **rAjAnau राजानौ

Wait, you said that **rAjan- राजन् is whimpy when it is before /Gas. Didn't you mean to say that /Gas is a whimpy affix?

No, I meant what I said. /Gas is not whimpy, **rAjan- राजन् before /Gas is. Careful with this!

Is /zas whimpy? Oopsie... I meant to say, does /zas make its stem whimpy?

That depends. /zas starts with a अ. If the base is a neuter, /zas will be strong, so **nAman- नामन् n before /zas isn't whimpy, and gets to keep its a अ —

**nAman- नामन् + /zas → nAman नामन् + /zI → **nAmAni नामानि

But if the base is m or f , like **rAjan- राजन् m , it will be whimpy, because /zas is not strong after it, so **rAjan- राजन् loses a अ by alloponaH —

**rAjan- राजन् + /zas → **rAjJas राज्ञस्

**rAjan- राजन् + /Gas → **rAjJas राज्ञस्

**rAjan- राजन् + /os → !**rAjJos राज्ञोस्

**rAjan- राजन् + /os → !**rAjJAm राज्ञाम्
