The Talmud Yerushalmi came to us full of textual errors and without traditional commentary. One way to correct this situation is through the study of the terminology of the Yerushalmi, which often is the key for interpreting a Talmudic sugyah. Thus, linguistic and semantic clarifications of Talmudic terms can assist the scholar in correcting faulty textual versions and enable him to come much closer to the original text of the Yerushalmi and to its accurate interpretation. The present three-volume Concordance provides scholars with a unique research tool to achieve these goals.
