Ge'ez script
Its mature form was reached around 800 BCE, and its use continued until the 6th century CE, including Ancient North Arabian inscriptions in variants of the alphabet, when it was displaced by the Arabic alphabet. In Ethiopia and Eritrea it evolved later into the Ge'ez script, which, with added symbols throughout the centuries, has been used to write Amharic, Tigrinya and Tigre, as well as other languages (including various Semitic, Cushitic, and Nilo-Saharan languages).
