Soyombo Cluster-Initial Letter Sa

It writes sa at the start of a Soyombo consonant cluster. A cluster joins consonants without a vowel between them; this small form attaches to the next consonant, the cluster’s base.

Soyombo was created in 1686 by Zanabazar for Mongolian writing; it was also used for Sanskrit and Tibetan. A manuscript page preserves this special form in Sanskrit and Tibetan cluster examples. The script is best known from Buddhist manuscripts and inscriptions in Central Asia.

Its design draws on Indic scripts (writing systems from South Asia), including Lantsa and Devanagari, and on Tibetan writing. Soyombo is historically related to Zanabazar Square, another script by the same creator. In the early 20th century, Soyombo writing also appeared on state seals; a separate Soyombo head mark became an independence emblem.

Why does this Soyombo sa look like a fragment?

It is a small starting form meant to join the next consonant.

Its compact geometric shape fits along the left side of the following consonant’s triangular frame; it has no matching full-size glyph. In a complete cluster, the following consonant supplies the base, and vowel signs attach to that base.

A font without Soyombo glyph or shaping support may show a box or leave the small form unjoined. The font and text renderer determine how the cluster is drawn.
