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. However, they were largely abandoned in Tifinagh, Latin and Cyrillic. The letter sequence continued
History of the Hebrew alphabet but following the rise of Christianity (and later, the rise of Islam), they gave way to the Latin and Arabic scripts, respectively. The Hebrew alphabet was later adapted in order to write down the languages of the Jewish diaspora (Karaim, Judæo-Arabic, Ladino, Yiddish, etc.), and was retained all the while in relatively unadapted form throughout the diaspora for Hebrew, which remained the language of Jewish law, scriptures and scholarship. The Hebrew alphabet was also retained as the alphabet used for writing down the Hebrew language during its rebirth as an everyday modern language starting in the 18th to 19th century.
