The Ancient South Arabian script (Old South Arabian 𐩣𐩯𐩬𐩵 ms3nd; modern Arabic: الْمُسْنَد musnad) branched from the Proto-Sinaitic script in about the 9th century BCE. It was used for writing the Old South Arabian languages Sabaic, Qatabanic, Hadramautic, Minaean, and Hasaitic, and the Ethiopic language Ge'ez in Dʿmt. The earliest inscriptions in the script date to the 9th century BCE in Yemen. There are no letters for vowels, which are marked by matres lectionis. 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).
