Among its descendants, the Ugaritic alphabet had 27 consonants, the South Arabian alphabets had 29, and the Phoenician alphabet 22. These scripts were arranged in two orders, an "ABGDE" order in Phoenician and an "HMĦLQ" order in the south; Ugaritic preserved both orders. Both sequences proved remarkably stable among the descendants of these scripts. The letter names proved stable among the many descendants of Phoenician, including Samaritan, Aramaic, Syriac, Arabic, Hebrew, and Greek alphabet.
