It is a secondary source that does not contain official pronouncements of the law
Black's Law Dictionary is a secondary source that explains the law and provides definitions of legal terminology and words in their legal sense. It is the most commonly used law dictionary in the United States and is often cited by courts when addressing the meaning of particular legal terms. The newly published 12th edition (2024) contains over 65,000 legal terms, each clearly and precisely defined in plain English.
While Black's Law Dictionary is a valuable resource, it is important to remember that it does not contain official pronouncements of the law. It is not an authoritative statement of the law but rather a tool to aid in understanding legal terminology. Legal dictionaries, like all secondary sources, provide commentary and analysis of the law but do not establish the law itself. They are meant to help researchers understand the terminology used in primary sources of law, such as case law, statutes, rules, and regulations.
Black's Law Dictionary offers more than just definitions. It provides references to relevant primary law sources, such as the West American Digest System, which can be useful for legal research. It also includes appendices with additional legal information, such as a list of legal abbreviations, a reprint of the U.S. Constitution, and a "legal maxims" section explaining established principles of law in Latin.
The dictionary is widely accessible, with print and online versions available. It can be found in law libraries, universities, and public libraries, as well as online databases such as Westlaw and LexisNexis. While Black's Law Dictionary is a trusted and widely used resource, it should be used as a starting point for research rather than the final authority on legal definitions and interpretations.
In conclusion, Black's Law Dictionary is a valuable secondary source that plays a crucial role in legal research and understanding legal terminology. However, it is essential to recognize that it does not contain official pronouncements of the law and should be used alongside other primary and secondary sources to gain a comprehensive understanding of legal concepts.
