The Mishnah or the Mishna (ˈmɪʃnə; מִשְׁנָה, 'study by repetition', from the verb shanah , or 'to study and review', also 'secondary') is the first major written collection of the Jewish oral traditions that are known as the Oral Torah. It is also the first major work of rabbinic literature. The Mishnah was redacted by Judah ha-Nasi probably in Beit Shearim or Sepphoris between the ending of the second century and the beginning of the 3rd century CE in a time when, according to the Talmud, the persecution of Jews and the passage of time raised the possibility that the details of the oral traditions of the Pharisees from the Second Temple period (516 BCE – 70 CE) would be forgotten. Most of the Mishnah is written in Mishnaic Hebrew, but some parts are in Aramaic.
The Mishnah consists of six orders (sedarim, singular seder סדר), each containing 7–12 tractates (masechtot, singular masechet מסכת; lit. 'web'), 63 in total, and further subdivided into chapters and paragraphs. The word Mishnah can also indicate a single paragraph of the work, i.e. the smallest unit of structure in the Mishnah. For this reason the whole work is sometimes referred to in the plural form, Mishnayot.
List of Talmudic tractates
The term "Mishnah" originally referred to a method of teaching by presenting topics in a systematic order, as contrasted with Midrash, which followed the order of the Bible. As a written compilation, the order of the Mishnah is by subject matter and includes a much broader selection of halakhic subjects and discusses individual subjects more thoroughly than the Midrash.
The Mishnah consists of six orders (sedarim, singular seder סדר), each containing 7–12 tractates (masechtot, singular masechet מסכת; lit. "web"), 63 in total. Each masechet is divided into chapters (peraqim, singular pereq) and then paragraphs (mishnayot, singular mishnah). In this last context, the word mishnah means a single paragraph of the work, i.e. the smallest unit of structure, leading to the use of the plural, "Mishnayot", for the whole work.
