Siddham Letter Na

It is the Siddham consonant na, usually read with an inherent a.

On its own, read it as na. A vowel sign changes the syllable; the virama removes the built-in a and leaves the consonant n. Siddham consonants can join into conjuncts—combined forms that may be stacked vertically, written side by side, or drawn as ligatures, single shapes made from joined letters.

How did Siddham reach East Asia?

It developed in northern India and traveled with Buddhist Sanskrit.

Siddham's surviving North Indian inscriptional record reaches back to sixth-century examples. The script also had historical names such as Siddhamatrika and Kutila. From the eighth century, related forms developed toward Sharada, Gauḍī, Proto-Bengali, and Nāgarī. A Dunhuang manuscript from that period preserves a Siddham version of a Sanskrit dharani, a Buddhist protective chant, alongside a Sogdian transcription of its sounds.

Writing Sanskrit helped preserve the sounds of Buddhist incantations. Chinese Buddhist readers kept the Indic script for those words instead of relying only on Chinese transcription. Siddham also appears in Indian inscriptions; its East Asian manuscript record is especially tied to Buddhist Sanskrit.

What does Bonji use mean in Japanese Buddhism?

Bonji is Siddham used in Japanese Buddhist ritual art and writing.

In Japanese Shingon and Tendai Buddhism, a character may spell a Sanskrit syllable or serve as a seed syllable—a written sign associated with a Buddhist deity. Not every character names a deity: 𑖡 may simply provide a sound, and the surrounding mantra or image helps show which role it has.

This ritual use is one later East Asian continuation of a script that also recorded Sanskrit words and texts.
