One of the most comprehensive dictionaries on the Hebrew language. Highly recommended for anyone serious about studying the Hebrew language of the Bible.

I am owning this work since 1969. I find it exhaustive, well organized, a treasure to hunt for rare words and expressions. It may not contain any new terms since around 1990, but with it you can translate anything you find in the Hebrew bible, or the Talmud.

The Alcalay dictionaries are absolutely unparalleled research tools. In my graduate department, students arrive early in the morning in the hopes of being the one to snag the Alcalay. These dictionaries are invaluable to both casual students and serious scholars of Hebrew. Each entry contains not only a careful philology/etymology of the word, but also an exhaustive, well-organized list of common phrases which incorporate the word, as well as differing usages. Biblical references, which are so important to understanding Hebrew usage, are provided, but Alcalay (now his son) also has his ear tuned to the street, and includes popular/slang meanings. For a language which evolves as quickly and as often as Hebrew, this is really critical. Unlike many other Hebrew-English dictionaries, which are often inconsistent in including or omitting vowels from the Hebrew, Alcalay is logical and consistent, so you always know where to look, and which form of the verb to look up. I may seem to be going overboard here, but I am a very serious student of Hebrew, and I can't praise the Alcalay dictionaries enough. Anything else is really a waste of money.
