History of the alphabet many letters the Proto-Sinaitic alphabet had nor what their alphabetic order was. 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.

The Arabic and Hebrew alphabets have similarities because they are both derived from the Aramaic alphabet. A distinct Hebrew variant of the Phoenician script, called by scholars the paleo-Hebrew alphabet, emerged around 800 BCE. Examples of related early inscriptions from the area include the tenth-century Gezer calendar, and the Siloam inscription (c. 700 BCE). The paleo-Hebrew alphabet was used in the ancient kingdoms of Israel and Judah.
