A comprehensive legal dictionary adds to its body of standard English entries many words and phrases that have made their way into modern legal practice from law French and Latin and are rarely found in a general English monolingual dictionary. Such a specialized dictionary is useful not only for law students and for attorneys themselves, but for members of the lay public who require legal services. Legal dictionaries published in print follow the normal practice of sorting entry terms alphabetically, while electronic dictionaries, such as the online Dictionary of Law on Dictionary.com, allow direct, immediate access to a search term.
