When a vowel in a sUtra has t त् added after it, it has only its own time.

Exception to < aNuditsav....

So the nounbase at अत् in a sUtra means short a अ — as in adeGguNaH.

and the nounbase At आत् in a sUtra means long A आ — as in vRddhirAdaic.

but the nounbase a अ in a sUtra means a अ or A आ by < aNuditsav....

Now I'm confused... You told me in the first lessons that the At आत् in sUtra AdguNaH means "after a अ or A आ", and now you say that At आत् means only "long A आ"?

This At आत् of AdguNaH is formed like thias —

nounbase a अ + /Gasi → a अ + At आत् by TAGasiGas... → word At आत्,

so it means "after a अ or A आ". The At आत् in vRddhirAdaic is a nounbase and means "long A आ".
