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.

The Aramaic alphabet was widely adopted for other languages and is ancestral to the Hebrew, Syriac and Arabic alphabets.
Yer A yer is one of two letters in Cyrillic alphabets: ъ (ѥръ, "jerŭ") and ь (ѥрь, "jerĭ"). The Glagolitic alphabet used, as respective counterparts, the letters and . They originally represented phonemically the "ultra-short" vowels in Slavic languages, including Old Church Slavonic, and are collectively known as the yers. In all modern Slavic languages, they either evolved into various "full" vowels or disappeared, in some cases causing the palatalization of adjacent consonants. The only Slavic language that still uses "ъ" as a vowel sign (pronounced /ɤ/) is Bulgarian, but in many cases, it corresponds to an earlier "ѫ", originally pronounced /õ/. Many languages that use the Cyrillic alphabet have kept one or more of the yers to serve specific orthographic functions.
