But not before /sambuddhi.

Exception to < nalopaHprAt....

So, the n न् will stay —

rAjan- राजन् + /sambuddhi
→ rAjans राजन्स्
→ rAjan राजन्, by halGyAbbhyodIrgh...
(< nalopaHprAt... debarred by this rule)
→ !**rAjan' राजन्ऽ "hi king"

As in vismayo me mahAn rAjan hRSyAmi ca punaH punaH विस्मयो मे महान्राजन्हृष्यामि च पुनः पुनः.

he yogin हे योगिन् "hey yogi"
he daNDin हे दण्डिन् "hey you the guy with the stick!" / "o wielder of the judicial, executive and legislative powers!"

By a /vArttika, this rule is optional after a neuter:

he bahuyogin vana हे बहुयोगिन्वन "O forest with many yogis!"

he bahuyogi vana हे बहुयोगि वन "O forest with many yogis!"

What is /Gi doing in the sUtra? Looks like you didn't translate it.

vedic rule. It applies only when /Gi is luked by supAMsulukp.... Forget it, or see candravasu.
