Tractate
A tractate (Hebrew:מסכת, Sephardic:/mɑː.ˈsɛ.xɛt/, Ashkenazic:/mɑː.ˈsɛ.xɛs/) is an organizational element of Talmudic literature (e.g. Mishnah, Tosefta, Beraita, Gemara).
The "major" tractates, which are those of the Mishnah itself, are organized into six groups, called sedarim, while the minor tractates, which were not canonized in the Mishnah, stand alone.
