ゲエズ語
In terms of writing systems, Ethiopia's principal orthography is Ge'ez or Ethiopic. Employed as an abugida for several of the country's languages, it first came into usage in the 6th and 5th centuries BC as an abjad to transcribe the Semitic Ge'ez language. Ge'ez now serves as the liturgical language of the Ethiopian and Eritrean Orthodox Churches. Other writing systems have also been used over the years by different Ethiopian communities. The latter include Sheikh Bakri Sapalo's script for Oromo.
