ami pUrvaH अमि पूर्वः ONPANINI 61107

Merge an /ak with /am into the former.

Or if you prefer —

/am loses a अ after all vowels except ai ऐ au औ.

Exception to <<<<< prathamayoHp..., which would lengthen as well. Before this m म्, the short stay short —

**rAma- रामॱ m + /am → !**rAmam रामम्

**putra- पुत्रॱ m + /am → !**putram पुत्रम्

**phala- फलॱ m + /am → **phalam फलम्

**kumbha- कुम्भॱ m + /am → !**kumbham कुम्भम् " o jar"

**guru- गुरुॱ m + /am → !**gurum गुरुम्

**RSi- ऋषिॱ m + /am → !**RSim ऋषिम्

**mati- मतिॱ f + /am → !**matim मतिम्

and the long stay long —

**nadI- नदीॱ f + /am → !**nadIm नदीम् " o river"

**devI- देवीॱ f + /am → !**devIm देवीम् " o goddess"

**azvA- अश्वाॱ f + /am → !**azvAm अश्वाम् " o mare"

**khaTvA- खट्वाॱ f + /am → !**khaTvAm खट्वाम् " o bed"

**vadhU- वधूॱ f + /am → !**vadhUm वधूम् " o wife"

This rule is overriden after some roots by eranekAc... —

**grAmaNI- ग्रामणीॱ mf + /am → **grAmaNyam ग्रामण्यम्

What about R ऋ-enders?

This rule won't work after R ऋ because RtoGisarv... works first, making the base end in a consonant —

**pitR- पितृॱ m + /am
→ pitar- पितर् + /am by RtoGisarv...
→ **pitaram पितरम्

svasR- स्वसृॱ f + /am → **svasAram स्वसारम् " o sister"

Why do we say "/ak"?

/am stays after /nau- /rai- —

/nau- + /am → **nAvam नावम्

/rai- + /am → **rAyam रायम्

But the o ओ in /go- /dyo- becomes A आ by <14 automzasoH, and then amipUr अमिपूर् catches the A आ —

/go- + /am → gA- गाॱ + /am → **gAm गाम्
