@abs inria

When inria paints a word pink and diagnoses it as "abs.", that means that the word has /ktvA after a root. Examples —

If you feed bhUtvA भूत्वा into inria it says in pink " ( abs. ) (bhU_1)". That means —

bhU भू + /ktvA → !**bhUtvA भूत्वा "after becoming", "(he, we...) became and..."

Now, with sannyasya सन्न्यस्य, you get a pink box with "abs. (sam-ni-as_2)". This means —

/sam + /ni + root /asyati + /ktvA → **sannyasya सन्न्यस्य "after renouncing"

I was expecting sannyastvA. How come /ktvA became ya य?

See /lyap.

What's the number after the root mean?

It's the number of the sense in the inria dictionary —

as_2 means that the root is /asyati "throw"
(as_1 would mean that the root is /as "be there")
bhU_1 means the /bhvAdi root bhU भू that means "be"
bhU_2 means "the Earth"

Neither do I, but I paste words from there into google translator.
