Mishnaic Hebrew is the Hebrew of Talmudic texts. Mishnaic Hebrew can be sub-divided into Mishnaic Hebrew proper (also called Tannaitic Hebrew, Early Rabbinic Hebrew, or Mishnaic Hebrew I), which was a spoken language, and Amoraic Hebrew (also called Late Rabbinic Hebrew or Mishnaic Hebrew II), which was a literary language only.

The Mishnaic Hebrew language, or Early Rabbinic Hebrew language, is one of the direct ancient descendants of Biblical Hebrew as preserved after the Babylonian captivity, and definitively recorded by Jewish sages in writing the Mishnah and other contemporary documents.

A transitional form of the language occurs in the other works of Tannaitic literature dating from the century beginning with the completion of the Mishnah. These include the halachic Midrashim (Sifra, Sifre, Mechilta etc.) and the expanded collection of Mishnah-related material known as the Tosefta. The Talmud contains excerpts from these works, as well as further Tannaitic material not attested elsewhere; the generic term for these passages is Baraitot. The language of all these works is very similar to Mishnaic Hebrew.
