The Phoenician alphabet (c. 1050 BC) is a direct descendant of Proto-Sinaitic. Proto-Sinaitic and Phoenician were abjads which only had letters representing consonantal sounds; Phoenician was ultimately adapted into the Greek alphabet (c. 800 BC), the first to represent vowel sounds, which it did by re-purposing unused Phoenician consonantal signs.[4] The Cumae alphabet, a variant of the early Greek alphabet, gave rise to the Etruscan alphabet and its own descendants, such as the Latin alphabet. Other descendants from the Greek alphabet include Cyrillic, used to write Bulgarian and Russian, among other languages. The Phoenician alphabet was also adapted into the Aramaic script, from which the Hebrew and the Arabic scripts are descended.[citation needed]
