Black’s Law Dictionary contains over 43,000 definitions and costs $49.99. Nolo’s Plain English Law Dictionary contains contains over 3,000 definitions written in plain English and is free.
The Barron’s law Dictionary application fits neatly between these two offerings. Like the Nolo dictionary, the Barron’s dictionary contains over 3,000 terms. Like Black’s, the Barron’s dictionary has more sophisticated definitions, although in my random check they seem to use less legalese than Black’s. And the price of $14.99 fits between the other two dictionaries.
