The Mishnah or the Mishna (/ˈmɪʃnə/; Hebrew: מִשְׁנָה, "study by repetition", from the verb shanahשנה, or "to study and review", also "secondary")[1] 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.[2] The Mishnah was redacted by Judah ha-Nasi probably in Beit Shearim or Sepphoris[3] between the ending of the second century and the beginning of the 3rd century CE[4][5] in a time when 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.
^The same meaning is suggested by the term Deuterosis ("doubling" or "repetition" in Koine Greek) used in Roman law and Patristic literature. However, it is not always clear from the context if the reference is to the Mishnah or the Targum, which could be regarded as a "doubling" of the Torah reading.
