Ezana's Innovation: How an Abjad Became an Abugida

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

For its first several centuries, the script that became Ge'ez recorded only consonants, an abjad in the same family as its ancestor, the Ancient South Arabian script carried across the Red Sea from the Sabaean kingdom of what is now Yemen. That changed by around the fourth century CE, during the reign of King Ezana of Aksum, whose trilingual inscriptions, in Ge'ez, Sabaean and Greek, include the earliest fully vocalized Ge'ez texts known, meaning the first to consistently mark vowel sounds rather than leave them to the reader's memory. The method Ge'ez scribes settled on was to modify each base consonant sign with small strokes, loops or stem extensions, one distinct variant for each of seven vowel sounds, turning every consonant into a compact family of seven related characters that share an obvious structural resemblance. This transformed Ge'ez into an abugida, structurally similar in principle to the Brahmi-derived scripts of India developing on the far side of the same historical moment, though there is no evidence of direct contact between the two traditions. The change also appears to have coincided with a shift in writing direction, from an earlier right to left orientation to the left to right convention Ge'ez and its descendants still use today.
