The Talmud (; ) is the central text of Rabbinic Judaism and the primary source of Jewish religious law (halakha) and Jewish theology. Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.

It may also traditionally be called (), a Hebrew abbreviation of , or the "six orders" of the Mishnah.

The Talmud is the basis for all codes of Jewish law and is widely quoted in rabbinic literature. Etymology Talmud translates as "instruction, learning", from the Semitic root , meaning "teach, study". History Originally, Jewish scholarship was oral and transferred from one generation to the next. Rabbis expounded and debated the Torah (the written Torah expressed in the Hebrew Bible) and discussed the Tanakh without the benefit of written works (other than the Biblical books themselves), though some may have made private notes (), for example, of court decisions. This situation changed drastically due to the Roman destruction of the Jewish commonwealth and the Second Temple in the year 70 and the consequent upheaval of Jewish social and legal norms. As the rabbis were required to face a new reality—mainly Judaism without a Temple (to serve as the center of teaching and study) and total Roman control over Judaea, without at least partial autonomy—there was a flurry of legal
