Shlomo Yitzchaki (; ; , 22 February 1040 – 13 July 1105), today generally known by the acronym Rashi, was a medieval French rabbi, the author of comprehensive commentaries on the Talmud and Hebrew Bible. Acclaimed for his ability to present the basic meaning of the text in a concise and lucid fashion, Rashi's commentaries appeal to both learned scholars and beginning students, and his works remain a centerpiece of contemporary Torah study. A large fraction of rabbinic literature published since the Middle Ages discusses Rashi, either using his view as supporting evidence or debating against it. His commentary on the Talmud, which covers nearly all of the Babylonian Talmud, has been included in every edition of the Talmud since its first printing by Daniel Bomberg in the 1520s. His commentaries on the Tanakh—especially his commentary on the Chumash (the "Five Books of Moses")—serves as the basis of more than 300 "supercommentaries" which analyze Rashi's choice of language and citations, penned by some of the greatest names in rabbinic literature. Name Rashi's surname, Yitzhaki, derives from his father's name, Yitzhak. The acronym "Rashi" stands for Rabbi Shlomo Yitzhaki, but is sometimes fancifully expanded as Rabban Shel YIsrael which means the "Rabbi of Israel", or as Rabbenu SheYichyeh (Our Rabbi, may he live). He may be cited in Hebrew and Aramaic texts as (1) "Shlomo son of Rabbi Yitzhak", (2) "Shlomo son of Yitzhak", (3) "Shlomo Yitzhaki", and myriad similar highly respectful derivatives. In older literature, Rashi is sometimes referred to as Jarchi or Yarhi (), his abbreviated name being interpreted as Rabbi Shlomo Yarhi. This was understood to refer to the Hebrew name of Lunel in Provence, popularly derived from the occitan luna "moon", in Hebrew , in which Rashi was assumed to have lived at some time or to have been born, or where his ancestors were supposed to have originated. Later Christian writers Richard Simon and Johann Christoph Wolf claimed that only Christian scholars referred to Rashi as Jarchi, and that this epithet was unknown to the Jews. Bernardo de Rossi, however, demonstrated that Hebrew scholars also referred to Rashi as Yarhi. In 1839, Leopold Zunz showed that the Hebrew usage of Jarchi was an erroneous propagation of the error by Christian writers, instead interpreting the abbreviation as it is understood today: Rabbi Shlomo Yitzhaki. The evolution of this term has been thoroughly traced. Biography Birth and early
