eGaH padAntAd ati

एङः पदान्तादति ONPANINI 61109

(Merge) padafinal e ए o ओ with a अ (into e ए o ओ).

Exception to ecoyavAyAvaH.

**udyAne उद्याने + **atra अत्र → !**udyAnetra उद्यानेत्र "in this garden"

viSNo विष्णो + ava अव → vISNova वीष्णोव "go away, viSNu विष्णु!"

azvas अश्वस् + atra अत्र → azvo अश्वो + atra अत्र → **azvotra अश्वोत्र

te ते + api अपि → !**tepi तेपि "they too"

It is a good idea for beginners to always write an /avagraha symbol where the a अ used to be:

udyAne 'tra उद्याने ऽत्र
viSNo 'va विष्णो ऽव
azvo 'tra अश्वो ऽत्र
te 'pi ते ऽपि

What does the /avagraha symbol mean?

It means "there used to be an a अ here, but rule this rule ate it up".

Why do we say "padafinal"?

When not padafinal, ecoyavAyAvaH will apply instead —

ne ने + a अ + ti ति → **nayati नयति

/go- + /Am → **gavAm गवाम्

Why do we say "e ए o ओ"?

ecoyavAyAvaH works normally after ai ऐ au औ before all vowels —

/nau'' + avatu अवतु → !**nAvavatu नाववतु

tasmai तस्मै + akSipat अक्षिपत्
→ tasmAyaksipat तस्मायक्सिपत् by ecoyavAyAvaH
→ !**tasmA::aksipat तस्मा‌अक्सिपत् by lopazzAkaly...

Why do we say "before a अ"?

Before other vowels, ecoyavAyAvaH will work normally —

vAyo वायो + iti इति → vAyaviti वायविति

sarve सर्वे + eva एव
→ sarvay eva सर्वयेव by ecoyavAyAvaH
→ !**sarva::eva सर्व‌एव optionally by lopazzAkaly...

Wait, why didn't **nAvavatu नाववतु above get lopazzAkaly...?

IDK, really. In the /pANini system rule lopazzAkaly... is optional. Yet if you trust printed books, it appears to be compulsory after av अव् ay अय् Ay आय् and forbidden after Av आव् —

oM saha nAv avatu ओं सह नाववतु — never nA::avatu ना‌अवतु.
sarva::eva सर्व‌एव — never sarvayeva सर्वयेव

Why doesn't sUtra ubhe::abhyast... show the effects of this rule?

Because of the exception IdUdeddviv... —

azve:: atra अश्वे‌ अत्र "two mares are here"

ubhe:: उभे‌ abhyastam "both together are called /abhyasta"

pacyete:: adya पच्येते‌ अद्य "both are being cooked today"
