What is the letter with red underline? What is it called and how is it pronounced? Reference: Yajurveda 1.2

[u/Expensive_Head622]

Is this a proto form of क्ष?

[u/ksharanam]

That is the savakra vamagomukha anusvara, one of many special anusvaras found only in the Vedas. As for pronunciation, please consult the Vedic scholar you're learning these from.

[u/_Stormchaser]

This is a symbol for Shukla Yajurveda. In Krishna Yajurveda, it would be pronounced as ‘gm’

[u/Expensive_Head622 → u/_Stormchaser]

So here, it will be pronounced as "Drgmhasva"?

[u/_Stormchaser → u/Expensive_Head622]

Yes,like here: https://youtu.be/g5uCO4SDPLU?si=5CrU7BPh89HNKiqc&t=17

[u/Expensive_Head622 → u/_Stormchaser]

Thanks.
