A Savora (Hebrew: [savoˈʁa]; Aramaic: סבורא, "a reasoner", plural Savora'im, Sabora'im [savoʁaˈʔim], סבוראים) is a term used in Jewish law and history to signify one among the leading rabbis living from the end of period of the Amoraim (around 500 CE) to the beginning of the Geonim (around 600 CE). As a group they are also referred to as the Rabbeinu Sevorai or Rabanan Saborai, and may have played a large role in giving the Talmud its current structure. Modern scholars also use the plural term Stammaim (Hebrew; "closed, vague or unattributed sources") for the authors of unattributed statements in the Gemara.
Much of classical rabbinic literature generally holds that the Babylonian Talmud was redacted into more or less its final form around 550 CE. In the introduction to his Mishnah Torah, Maimonides writes that Rav Ashi compiled the Babylonian Talmud. He also writes that Ravina and Rav Ashi (Amoraim, who are mentioned in the Talmud) were the final sages of Israel who transcribed the Oral Torah. However, some statements within classical rabbinic literature, and later analysis thereof, have led many scholars to conclude that the Babylonian Talmud was smoothed over by the Savora'im, although almost nothing was changed. Occasionally, multiple versions of the same legalistic discussion are included with minor variations. The text also states that various opinions emanated from various Talmudic academies.
Sherira Gaon (c.987 CE) indicates that Rav Yose was the final member of the Savora'im. Occasionally, specific Savora'im are mentioned by name in the Talmud itself, such as Rabbi Ahai, who (according to later authority Rashbam) was a Savora.
