It is similar to the Mishnah, but contains additional material that was not included in the Mishnah. There are several synonyms for the word tosefta, including addition, supplement, and enlargement. These words all imply that the Tosefta is a complementary work to the Mishnah. Another synonym for Tosefta is 'Beraita'. Beraita is a rabbinic tradition that was supposed to have been taught by rabbis who were contemporaneous with the authors of the Mishnah or earlier. This term is often used interchangeably with Tosefta. Whatever the synonyms are, the Tosefta remains an important text in the study of Jewish law and tradition.
