Amora (Aramaic: אמורא; plural אמוראים, Amora'im; "those who say" or "those who tell over"), were renowned Jewish scholars who "said" or "told over" the teachings of the Oral law, from about 200 to 500 CE 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.
The Amoraic era
The first Babylonian Amoraim were Abba Arika, respectfully referred to as Rav, and his contemporary and frequent debate partner, Shmuel. Among the earliest Amoraim in Israel were Rabbi Yochanan and Shimon ben Lakish. Traditionally, the Amoraic period is reckoned as seven or eight generations (depending on where one begins and ends). The last Amoraim are generally considered to be Ravina I and Rav Ashi, and Ravina II, nephew of Ravina I, who codified the Babylonian Talmud around 500 CE.
In the Talmud itself, the singular amora generally refers to a lecturer's assistant; the lecturer would state his ts briefly, and the amora would then repeat them aloud for the public's benefit, adding translation and clarification where needed.
