NuBerea/jastrow-lexicon

A complete Public-Domain ingest of Marcus Jastrow's A Dictionary of the Targumim, the Talmud Babli and Yerushalmi, and the Midrashic Literature (London/New York, 1903) — the standard reference lexicon for the language of the Tannaitic, Amoraic, Targumic, and Midrashic corpora. It is the canonical PD witness lexicon for Tannaitic Hebrew, Targumic Aramaic (Onqelos / Yerushalmi / Pseudo-Jonathan), Babylonian Talmudic Aramaic, and Palestinian/Galilean Aramaic — registers that Biblical-Hebrew-only lexica (BDB, HALOT) deliberately omit.

The dataset covers the full alphabet: one row per Jastrow headword/sense-cluster, with definitions, citation references, and cross-language quotations as parsed by Sefaria. The full technical specification (schema, coverage tables, build provenance) is available in the gated SPEC.md alongside this card.
