Ge'ez (/ˈɡiːɛz/; ግዕዝ, Gəʿəz [ɡɨʕɨz]; also transliterated Gi'iz, and less precisely called Ethiopic) is an ancient South Semitic language that originated in Eritrea and the northern region of Ethiopia in the Horn of Africa. It later became the official language of the Kingdom of Aksum and Ethiopian imperial court.Today, Ge'ez remains only as the main language used in the liturgy of the Ethiopian Orthodox Tewahedo Church, the Eritrean Orthodox Tewahedo Church, the Ethiopian Catholic Church, and the Beta Israel Jewish community. However, in Ethiopia Amharic (the main lingua franca of modern Ethiopia) or other local languages, and in Eritrea and Tigray Region in Ethiopia, Tigrinya may be used for sermons. Tigrinya and Tigre are closely related to Ge'ez with at least four different configurations proposed. Some linguists do not believe that Ge'ez constitutes the common ancestor of modern Ethiopian languages, but that Ge'ez became a separate language early on from some hypothetical, completely unattested language, and can thus be seen an extinct sister language of Tigre and Tigrinya. The foremost Ethiopian experts such as Amsalu Aklilu point to the vast proportion of inherited nouns that are unchanged, and even spelled identically in both Ge'ez and Amharic (and to a lesser degree, Tigrinya).
