About “Arukh”
Nathan ben Jehiel of Rome was a Jewish Italian lexicographer who wrote the Arukh, a dictionary focused on Rabbinic Judaism. The Arukh was the first work to explore Jewish Babylonian Aramaic. Because of this, he is known as "the Arukh." His work served as an important reference for understanding the language used in Jewish religious texts. (Summary adapted from Wikipedia, CC BY-SA 4.0.)
