A question: Are there more examples of -dh- in second syllable
changing to -h- in IA languages?

Dadhi 'curd' and its IA variants

"dahi" is usually said to come from dadhi (Sanskrit). Is there any
other word where the second syllable -dh- changes to -h-??

@cobbaltt gave: Some examples of debuccalisation of breathy voiced or
aspirated consonants that come to my mind now - OIA vidʰávā > MIA
viɦavā OIA katʰā́ > MIA kahā (Hindi kəh-) OIA √labʰ 'to take, obtain'
> MIA √lah (Hindi le-) OIA saphala 'successful' > MIA sahala- Are
there any more examples? And any journal article references giving
this list?
------------------

tamil tOy(k)u- ("to ferment") > taki-/tayi(r). Note there is a related
word "takra" in Sanskrit also. DEDR 3088 Ta. tayir curds, tyre, brain
matter. Ma. tayir curds. / ? < Skt. takra- buttermilk mixed with
water. DED 2517.

Thanks, NG

Hello, this is a very well-known Middle-Indic sound change discussed even by grammarians like Hēmacandra. You will find it mentioned in any historical treatment of Indo-Aryan, e.g., Masica, Chatterji, Woolner, Pischel, etc.
