Dear Nina abd Sabrina,

Instead of the insertion of v which would be called an "aagama", one should
follow Kaccaayana's rule 18 (vamodantaana.m) where, in some cases, v is the
substitute (aadesa) of o or u at the end of a word and before a following
vowel. The lengthening of a in aaha.m is correct (Kacc 15).

Best wishes,
Jim

<< Dear Sabrina,

> khvaaha.m: kho+ aha.m

Kho is a particle for emphasis, transl. as: indeed.
Here a consonant is inserted between two vowels. A final o (kho)
followed by a: insertion of v. and then lenghtening of a: aaha.m.
I use Warder (Ch 23) for my Pali. see also: kho+ ettha-> khvettha. >>
