Mishnah is a compilation of legal opinions and debates. Statements in the Mishnah are typically terse, recording brief opinions of the rabbis debating a subject; or recording only an unattributed ruling, apparently representing a consensus view. The rabbis recorded in the Mishnah are known as the Tannaim (literally, "repeaters", or "teachers"). These tannaim—rabbis of the second century CE--"who produced the Mishnah and other tannaic works, must be distinguished from the rabbis of the third to fifth centuries, known as amoraim (literally, "speakers"), who produced the two Talmudim and other amoraic works". Since it sequences its laws by subject matter instead of by biblical context, the Mishnah discusses individual subjects more thoroughly than the Midrash, and it includes a much broader selection of halakhic subjects than the Midrash. The Mishnah's topical organization thus became the framework of the Talmud as a whole. But not every tractate in the Mishnah has a corresponding Gemara. Also, the order of the tractates in the Talmud differs in some cases from that in the Mishnah. Baraita In addition to the Mishnah, other tannaitic teachings were current at about the same time or shortly after that. The Gemara frequently refers to these tannaitic statements in order to compare them to those contained in the Mishnah and to support or refute the propositions of the Amoraim. The baraitot cited in the Gemara are often quotations from the Tosefta (a tannaitic compendium of halakha parallel to the Mishnah) and the Midrash halakha (specifically Mekhilta, Sifra and Sifre). Some baraitot, however, are known only through traditions cited in the Gemara, and are not part of any other collection. Gemara In the three centuries following the redaction of the Mishnah, rabbis in Palestine and Babylonia analyzed, debated, and discussed that work. These discussions form the Gemara. The Gemara mainly focuses on elucidating and elaborating the opinions of the Tannaim. The rabbis of the Gemara are known as (sing. ). Much of the Gemara consists of legal analysis. The starting point for the analysis is usually a legal statement found in a Mishnah. The statement is then analyzed and compared with other statements used in different approaches to biblical exegesis in rabbinic Judaism (or – simpler – interpretation of text in Torah study) exchanges between two (frequently anonymous and sometimes metaphorical) disputants, termed the (questioner) and (answerer). Another important function of Gemara is to identify the correct biblical basis for a
