Explanation of script details

Script description

Siddham is an extinct Brahmic script which was used between 600-1200 AD for writing Sanskrit.

Read the full description…The script originated in southern India but travelled along the silk road to China, Japan and Korea in the form of Buddhist tantra texts. An adaptation of the script is still used in some esoteric Buddhist schools in Japan, where it is called Bonji.

The script is an abugida. Each character indicates a syllable consisting either of an independent (that is, not preceded by a consonant) vowel, or of a consonant followed by the vowel /a/. Diacritic marks can be appended to consonant letters to indicate that a vowel other than /a/ follows. There is also a diacritic mark, the virama to indicate that a consonant stands alone, with no following vowel. Consonant clusters are usually written with special conjunct forms.
