Rabbis by rabbinical period

Tannaim (Amoraic Hebrew: , singular , borrowed from Aramaic) 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".

Geonim (, ; also transliterated as ; , ) were the chiefs of the Sura and Pumedita Academies, the two great Talmudic Academies in Babylonia during the Abbasid Caliphate. They were generally accepted as the spiritual leaders of the Jewish community worldwide in the Early Middle Ages, in contrast to the Resh Galuta () who wielded secular authority over the Jews in Islamic lands.

Amoraim ( , singular Amora ; "those who say" or "those who speak over the people", or "spokesmen") refers to Jewish scholars of the period from about 200 to 500 CE, who "said" or "told over" the teachings of the Oral Torah. They were primarily located in Babylonia and the Land of Israel. Their legal discussions and debates were eventually codified in the Gemara. The Amoraim followed the Tannaim in the sequence of ancient Jewish scholars. The Tannaim were direct transmitters of uncodified oral tradition; the Amoraim expounded upon and clarified the oral law after its initial codification.

In Jewish law and history, Acharonim (, , ; ; ) are the leading rabbis and poskim (Jewish legal decisors) living from roughly the 16th century to the present, and more specifically since the writing of the Shulchan Aruch (; a code of Jewish law) in 1563 CE.

Rishonim (; ; sing. , Rishon) were the leading rabbis and poskim who lived approximately during the 11th to 15th centuries, in the era before the writing of the Shulchan Aruch (, "Set Table", a common printed code of Jewish law, 1563 CE) and following the Geonim (589–1038 CE). Rabbinic scholars subsequent to the Shulchan Aruch are generally known as acharonim ("the latter ones").

Savora (; Aramaic: סבורא, "a reasoner", plural '''''Savora'im, Sabora'im''' , 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.
