The Aramaic alphabet is ancestral to what alphabet known variously by scholars as the Jewish script?
Aramaic language 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.
Targum (Aramaic dialects) Targum is used by the Jews of northern Iraq and Kurdistan to refer to a variety of Aramaic dialects spoken by them till recent times. For details of these dialects, see Judeo-Aramaic language. The word "targum" simply means "translation" in Hebrew, and the primary reference of the term is the Aramaic Bible translations of that name. The Jewish use of "Targum" to mean the Aramaic language in general dates back to the early Middle Ages. An analogy is the use of "Ladino" to mean Judeo-Spanish, and of "sharħ" to mean Judeo-Arabic.
