Text symbol

What 𑖋 means

It marks Sanskrit’s independent vowel ai.

Siddham, a Brahmi-derived script (Brahmi is an older South Asian script), arose around the 5th century. North Indian inscriptions show a regional Siddhamātrikā or Kuṭila style mainly from the 6th–10th centuries; from the 8th century, it branched into Sharada, Gauḍī (Proto-Bengali), and Nāgarī. Buddhist texts carried it to China, Korea, and Japan. As of 2026, Japanese Shingon and Tendai Buddhists use it in mantras and deity-linked seed syllables.

Liturgical.

Ritual context supplies deity or mantra meaning, not the letter alone.

Why does 𑖋 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
