MISNAH
“teaching, doctrine.” Around the year 200 AD, Rabbi Yehuda Ha-Nâsî set down in writing all the extra-biblical traditions found in the private records of his predecessors.
It is his work, written in the Neo-Hebrew language, containing Greek terms. and lat. Hebraized, the one that bears the name of Mishnah. He was soon recognized as an authority in rabbinic schools.
After the death of Yehuda Ha-Nâsî the need was felt to complete and explain the Mishnah. The two commentaries on the Mishna written by the Jewish doctors of the schools of Tiberias (Palestine) and Babylon are called Gemaras (definitive study).
These comments are written in Aramaic, one of them in the Galilean dialect and the other in the Babylonian. The Mishna and the Gemaras are the constituent elements of the Talmud
