Question: Which language's alphabet was widely adopted for other languages and is ancestral to Jewish language?
Context: The Dinka alphabet is used by South Sudanese Dinka people.  The written Dinka language is like Latin, but with some added letters adapted from the International Phonetic Alphabet to the ISO basic Latin alphabet.  The current orthography is derived from the alphabet developed for the southern Sudanese languages at the Rejaf language conference in 1928.  Prior to this, several attempts at adapting the Arabic and Latin scripts to the Dinka language were made, but neither effort was met with large success.  Christian missionaries were essential to the development of what became the Dinka alphabet. The Caucasian Albanian alphabet, or the alphabet for the Gargareans, was an alphabet used by the Caucasian Albanians, one of the ancient and indigenous Northeast Caucasian peoples whose territory comprised parts of present-day Azerbaijan and Daghestan.  It was one of only two indigenous alphabets ever developed for speakers of indigenous Caucasian languages (i.e. Caucasian languages that are not a part of larger groupings like the Turkic and Indo-European languages families) to represent any of their languages, the other being the Georgian alphabet.  The Armenian language, the third language of Caucasus with its own alphabet, is an independent branch of the Indo-European language family. The classical Latin alphabet, also known as the Roman alphabet, is a writing system originally used by the ancient Romans to write the Latin language.  The Latin alphabet evolved from the visually similar Cumaean Greek version of the Greek alphabet, which was itself descended from the Phoenician abjad, which in turn was derived from Egyptian hieroglyphics.  The Etruscans who ruled early Rome adopted the Cumaean Greek alphabet which was modified over time to become the Etruscan alphabet, which was in turn adopted and further modified by the Romans to produce the Latin alphabet. David Monson Bunis (Hebrew:, born June 3, 1952 to Jacob and Marsha Monsohn Bunis) is a professor in the Department of Hebrew and Jewish Languages, Mandel Institute of Jewish Studies, at the Hebrew University of Jerusalem and heads its program in Judezmo (or Ladino) studies.  He is also an advisor to the Israel Autoridad Nasionala del Ladino.  He is the editor of "Languages and Literatures of Sephardic and Oriental Jews" (Jerusalem, 2009), co-editor of "Massorot", a Hebrew-language journal devoted to the study of Jewish language traditions, and author of books and articles on the Judezmo language and its literature. The Proto-Slavic language, the hypothetical ancestor of the modern-day Slavic languages, developed from the ancestral Proto-Balto-Slavic language ( 1500 BC), which is the parent language of the Balto-Slavic languages (both the Slavic and Baltic languages, e.g. Latvian and Lithuanian).  The first 2,000 years or so consist of the pre-Slavic era, a long period during which none of the later dialectal differences between Slavic languages had yet happened.  The last stage in which the language remained without internal differences that later characterize different Slavic languages can be dated around AD 500 and is sometimes termed "Proto-Slavic proper" or "Early Common Slavic".  Following this is the Common Slavic period ( 500–1000), during which the first dialectal differences appeared but the entire Slavic-speaking area continued to function as a single language, with sound changes tending to spread throughout the entire area.  By around 1000, the area had broken up into separate East Slavic, West Slavic and South Slavic languages, and in the following centuries it broke up further into the various modern Slavic languages of which the following are extant: Belarusian, Russian, Rusyn and Ukrainian in the East; Czech, Slovak, Polish, Kashubian and the Sorbian languages in the West, and Bulgarian, Macedonian, Serbo-Croatian and Slovenian in the South. The Hebrew alphabet (Hebrew: אָלֶף־בֵּית עִבְרִי‎ , "Alefbet Ivri "), known variously by scholars as the Jewish script, square script and block script, is an abjad script used in the writing of the Hebrew language, also adapted as an alphabet script in the writing of other Jewish languages, most notably in Yiddish (lit.  "Jewish" for Judeo-German), Djudío (lit.  "Jewish" for Judeo-Spanish), and Judeo-Arabic.  Historically, there have been two separate abjad scripts to write Hebrew.  The original, old Hebrew script, is known as the paleo-Hebrew alphabet (which has been largely preserved, in an altered form, in the Samaritan alphabet), while the present "Jewish script" or "square script" to write Hebrew is a stylized form of the Aramaic alphabet and was known by Jewish sages as the Ashuri alphabet (lit.  "Assyrian"), since its origins were alleged to be from Assyria.  Various "styles" (in current terms, "fonts") of representation of the Jewish script letters described in this article also exist, as well as a cursive form which has also varied over time and place, and today is referred to as cursive Hebrew.  In the remainder of this article, the term "Hebrew alphabet" refers to the Jewish square script unless otherwise indicated. The Modern Filipino alphabet (Filipino: "Makabagong alpabetong Filipino" ), otherwise known as the Filipino alphabet (Filipino: "alpabetong Filipino" ), is the alphabet of the Filipino language, the official national language and one of the two official languages of the Philippines.  The Modern Filipino alphabet is made up of 28 letters, which includes the entire 26-letter set of the ISO basic Latin alphabet, the Spanish "Ñ" and the "Ng" digraph of Tagalog.  It replaced the Pilipino alphabet of the Fourth Republic.  Today, the Modern Filipino alphabet may also be used as the alphabet for all autochthonous languages of the Philippines and in writing Chavacano, a Spanish-derived creole. Judæo-Aragonese (Aragonese: Chodigo-Aragonés) was a Judæo-Romance language (a Jewish language derived from Aragonese), used by Spanish Jews in north-central Spain from the mid-8th century until the time of the Jewish expulsion from Spain, when it either merged with the various Judæo-Spanish dialects, or fell out of use in favor of the far more influential Judæo-Spanish.  While there are some scholars that believe that the language may have had some speakers until around the time of World War Two, most scholars believe that it went fully extinct in the Middle Ages.  Along with Judæo-Catalan, Judæo-Aragonese shares a marked component of Judæo-Greek.  It has been suggested that the reason for Judæo-Catalan's influence on Judæo-Aragonese's may be due to an influx of Judæo-Catalan speakers in the 14th century, especially around the times of the nationwide pogroms in 1391. Jewish languages are the various languages and dialects that developed in Jewish communities in the diaspora.  The original Jewish language is Hebrew, which was supplanted as the primary vernacular by Aramaic following the Babylonian exile.  Jewish languages feature a syncretism of indigenous Hebrew and Judeo-Aramaic with the languages of the local non-Jewish population. Aramaic (אַרָמָיָא "Arāmāyā", Syriac: ܐܪܡܝܐ‎ , Arabic: آرامية‎ ‎ ) is a language or group of languages belonging to the Semitic subfamily of the Afroasiatic language family.  More specifically, it is part of the Northwest Semitic group, which also includes the Canaanite languages such as Hebrew and Phoenician.  The Aramaic alphabet was widely adopted for other languages and is ancestral to the Hebrew, Syriac and Arabic alphabets.
