ऋत्विग्दधृक्स्रग्दिगुष्णिगञ्चुॱ युजिॱक्रुञ्चां च ONPANINI 32059

There is /kvin after
Rtvij- ऋत्विज् dadhRS- दधृष् sraj- स्रज् **diz- दिश् uSNih- उष्णिह्
/aJcu yuj- युज् kruJc क्रुञ्च्.

Here, Rtvij- ऋत्विज् dadhRS- दधृष् sraj- स्रज् **diz- दिश् uSNih- उष्णिह् always get /kvin, and it makes them get k क् replacement when padafinal —

**diz- दिश् f + /su
→ diz दिश् by halGyAbbhyodIrgh...
→ **dik दिक् by kvinpratyayasy... ff

The other three are rootnouns (aJc अञ्च् "being at", yuj युज् "yoke", kruJc क्रुञ्च् "approach") and only get /kvin sometimes.

yuJj युञ्ज् "yoked" and kruJc क्रुञ्च् are rootnouns that can be used alone, and they only get /kvin when alone, making the nounbases yuj- युज् kruj- क्रुज् (with loss of nasal by aniditAMh...). The /kvin makes them will get /num before strong by !! . —

yuj- युज् + /su → **yuG युङ् as in azvair yuG अश्वैर्युङ्

yuJjau युञ्जौ

yuJjas युञ्जस्

kruJc- क्रुञ्च् + /su → !**kruG क्रुङ् "curlew" , like **prAG प्राङ्

But when compounded we get **azvayuk अश्वयुक्, azvayujau अश्वयुजौ, azvayujas अश्वयुजस् with no /num.

Contrariwise, aJc अञ्च् gets /kvin only when ifc, making the rootnoun /ac''' of **pratyac- प्रत्यच् "western", **prAc- प्राच् "eastern", and **udac- उदच् "northern".
