@flat laG derivations

The flat laG are —

/t''' /tAm''' /jh'''
/s''' /tam''' /ta'''
/am''' /va''' /ma'''

Rules itazca, tasthasthamip... and nityaGGitaH for these from the flat laT (aka flat basic tiG) —

/laG /tip
→ /t''' by itazca

/laG /tas
→ /tAm''' by tasthasthamip...

/laG /jhi
→ /ant''' by itazca

/laG /sip
→ /s''' by itazca

/laG /thas
→ /tam''' by tasthasthamip...

/laG /tha
→ /ta''' by tasthasthamip...

/laG /mip
→ /am''' by tasthasthamip...

/laG /vas
→ /va''' by nityaGGitaH

/laG /mas
→ /ma''' by nityaGGitaH

The /jh''' will change into /ant''' by jhontaH or into /jus by sijabhyastav....

Back to flat laG.

To derive these, start with the nine basic endings from the tiptasjhisipth... list —

/tip /tas /jhi
/sip /thas /tha
/mip /vas /mas

Then —

rule tasthasthamip... replaces /tas /thas /tha /mip,
itazca drops the i of /tip /sip /jhi,
and nityaGGitaH chops off the s of /vas /mas.
