Grantha Letter Vedic Double Anusvara

It marks a doubled Vedic anusvara in the Krishna Yajur Veda. An anusvara is a nasal-sound sign. A Unicode proposal calls this the Dvir Bhuta Lupta Agama Anusvara, a technical name for the specialized doubled notation; it is not two ordinary marks or a general nasalization sign.

Intermediate forms of Grantha appear in fourth-century CE Pallava inscriptions; the modern form of the script belongs to after the thirteenth century. That timeline describes Grantha’s development, not the first appearance of 𑍟.

Why does 𑍟 appear in Grantha Vedic texts?

It belongs to specialist Vedic Sanskrit transcription in Grantha. It appears in teaching, study, scholarship, and religious practice, chiefly in Tamil Nadu, with use also reported elsewhere in India and Sri Lanka. Its presence identifies a textual tradition to preserve, rather than an ornamental mark to improvise.

Grantha’s Vedic anusvara pair includes 𑍞, the single form, and 𑍟, the doubled form assigned to the Krishna Yajur Veda.

Are Vedic Grantha anusvara signs interchangeable?

No; their roles differ by sign and Vedic tradition. The ordinary Grantha anusvara is 𑌂. The Unicode proposal reports that some Sāmaveda printings use 𑍞 for the usual anusvara, while 𑌂 can stand for a nasal made at the same place in the mouth as the next consonant; it says the practice varies. That convention is separate from 𑍟’s assignment as the doubled form in the Krishna Yajur Veda.
