इषुॱगमिॱयमां छः ONPANINI 73077

Replace iS इष् gam गम् yam यम् with ch छ् before /zit.

So, before /zap, we get —

iS इष् + /laT
→ iS इष् + /zap + /laT by kartarizap
→ ich इछ् + a अ + /laT by this rule
→ !**iccha- इच्छॱ + /laT by checa

and similarly —

!**gaccha- गच्छॱ

!**yaccha- यच्छॱ

so we say —

iS इष् + /laT /tip
→ **iccha- इच्छॱ + /tip
→ !**icchati इच्छति "wants"

gam गम् + /laT /tip → !**gacchati गच्छति

gam गम् + /laT /mip → !**gacchAmi गच्छामि

gam गम् + /laT /mas → !**gacchAmas गच्छामस्

!**agacchat अगच्छत्

!**gaccha गच्छ

!**gacchet गच्छेत्

!**yacchati यच्छति

But the /liT, by liTca, is soft, therefore it does not insert /zap, and the lack of /zit makes the m म् S ष् stay —

**jagAma जगाम
yayAma ययाम
**iyeSa इयेष

And the same thing happens when a tense does not show the doer —

gam गम् + objectshowing /laT /ta
→ gam गम् + /yak + /ta
→ !**gamyate गम्यते "it is gone to"

gam गम् + nothingshowing /laT /ta
→ gam गम् + /yak + /ta
→ !**gamyate' गम्यतेऽ "someone goes"
