Phoenician alphabet
The Phoenician alphabet is a Northwest Semitic consonantal writing system (abjad) of 22 letters, written right to left and used across the eastern and central Mediterranean in the early 1st millennium BCE. Developed from Proto‑Canaanite/Proto‑Sinaitic antecedents, it became a principal ancestor of later scripts, notably Greek and Aramaic, and through them influenced many modern writing systems.
