This dictionary is an absolute must for anyone learning Gemara or any other Aramaic works.

Not only is every possible definition given, Jastrow brings down numerous examples of the usage of each word, ensuring a firm grasp of each word's nuances.

A classic and still standard resource, Marcus Jastrow's monumental dictionary remains unique in that it covers both the Hebrew and Aramaic languages in the literature of the rabbinic period. This indispensable dictionary of targumic and rabbinic literature includes thousands of entries in fully vocalized Hebrew and Aramaic, with references to the original texts, clear English definitions, and the full range of meanings and usages in the sources. It is organized alphabetically by actual form but includes also reference to a word's root, with abundant cross-references.
