Brahmi

Brahmi is the fountainhead of the Indic world's writing — nearly every script of South and Southeast Asia descends from it. It appears fully formed in the rock and pillar edicts of the emperor Ashoka in the 3rd century BCE, already a systematic abugida.

Its origin before that is the family's great open question. Many scholars derive it from Aramaic, carried east by trade or administration; others argue for a more independent, indigenous development. The institute records the Aramaic link but does not resolve it.

Two hundred scripts, one ancestor — whose own parent is still argued over.

What Brahmi unquestionably did was fix the template every descendant follows: a consonant letter carries a built-in 'a' vowel, and other vowels are written by modifying or attaching marks to it. See the descent diagram in the Hall of Lineages, where the Aramaic contest is flagged too.

In Brahmi the consonant 𑀓 is not a bare "k" but "ka" — the letter already carries an inherent a. To write another vowel you attach a vowel sign to the consonant, and to strip the vowel entirely you add a virama. This is the abugida principle, and Brahmi is where it begins.
