Tannaim (Hebrew: תנאים [tanaˈʔim], singular Hebrew: תנא [taˈna], Tanna "repeaters", "teachers") were the Rabbinic sages whose views are recorded in the Mishnah, from approximately 10-220 CE. The period of the Tannaim, also referred to as the Mishnaic period, lasted about 210 years. It came after the period of the Zugot ("pairs"), and was immediately followed by the period of the Amoraim ("interpreters").
The root tanna (אתנא) is the Talmudic Aramaic equivalent for the Hebrew root shanah (שנה), which also is the root-word of Mishnah. The verb shanah (שנה) literally means "to repeat [what one was taught]" and is used to mean "to learn".
