from The Century Dictionary and Cyclopedia

  • Ethiopic, called by its users the Ge'ez, usually written Geëz, the language of the Aga'azi, ‘emigrants’ from southern Arabia who had settled in Tigré (now a province of Abyssinia) about 335 a. d. Superseded by Amharic as the official language of the country about the year 1300, it has continued to be the liturgic language of the Abyssinian Church, somewhat as Latin in the Roman Catholic Church. Originally written, like the other Semitic languages, from right to left, the direction was early changed, under Greek influence, to the European order (from left to right). The alphabet consists of peculiar characters of Himyaritic origin. There is considerable literature, including an ancient translation of the Bible. The two principal modern representatives of Geëz are the dialects knowu as Tigré (Tigrē, Tigraï, native Tigraï), spoken by nomadic tribes in the extreme north, and
  • Tigriña, a more corrupt form largely mixed with Amharic words, as spoken in the old province of Tigré. The Hamitic family is represented in Abyssinia by Agau (Agou), spoken by a large number of Abyssinians and Tigré people, by Galla, and by many others.
