The Talmud (/ˈtɑːlmʊd, -məd, ˈtæl-/; Hebrew: תַּלְמוּד talmūd "instruction, learning", from a root lmd "teach, study") is a central text of Rabbinic Judaism. It is also traditionally referred to as Shas (ש״ס), a Hebrew abbreviation of shisha sedarim, the "six orders". The term "Talmud" normally refers to the collection of writings named specifically the Babylonian Talmud, though there is also an earlier collection known as the Jerusalem Talmud.
The Talmud has two components: the Mishnah (Hebrew: משנה, c. 200 CE), a written compendium of Rabbinic Judaism's Oral Torah (Talmud translates literally as "instruction" in Hebrew); and the Gemara (c. 500 CE), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Hebrew Bible. The term "Talmud" may refer to either the Gemara alone, or the Mishnah and Gemara together.
