Purpose and best uses
Statutory Definitions helps you find how the U.S. Code defines its own terms. It focuses on quoted statutory language, the provision containing the definition, and the scope within which that definition applies. Use it when a word's ordinary meaning may differ from its meaning in a particular federal law. This is a different task from looking up vocabulary in Legal Dictionary: the aim is to locate enacted definitional language and understand which part of the statutory scheme it belongs to.
The page provides a term-search field and a scope selector covering available federal titles. It describes definitions in terms of whether the language is exhaustive or open-ended and where the definition applies. Those distinctions are useful because the same word can appear in several federal programs with different meanings. A definition attached to one chapter or section should not automatically be carried into an unrelated provision. The source location and scope are therefore as important as the quoted words themselves.
How to use it well
Search the term and, when possible, narrow the scope to the title relevant to your question. Review multiple matches if the word is common. Compare the provision, surrounding subject, and scope language before deciding which entry is relevant. If a definition refers to another section, follow the available cross-reference and read the destination in context. Do not stop at the first occurrence merely because it uses the right word. The correct definition is the one that actually applies to the legal text you are interpreting.
Read qualifiers closely. A definition may include exceptions, references to other definitions, or language limiting its application to a specific part of the code. Use the displayed source to inspect surrounding provisions where needed. Save a useful definition to My List if you expect to return to it, and add a note identifying the section or issue you were studying. That note prevents a saved definition from becoming detached from the scope that made it relevant in the first place.
Example and practical limits
Imagine that a fictional research question turns on the word “employee.” An ordinary dictionary can explain the general idea, but Statutory Definitions can reveal several federal provisions using that term in different settings. Your task is to identify the relevant statutory scheme, choose the applicable definition, and then examine the source text and related provisions. Ask can help explain the relationship among those materials after you have established which definitions and sources are actually in issue.
The current tool is specifically a federal U.S. Code definition finder; its title should not be read as a promise that it covers every state statute, regulation, contract, or judicial definition. Availability in the tool also does not establish the current effective version of a provision. Check the official source and relevant dates when that matters to the work. Statutory Definitions is best used to avoid substituting an ordinary-language or historical meaning for a law's own wording. It supports precise reading and more focused research, but the surrounding statute, applicable edition, and any relevant interpretation still need attention before you draw a conclusion about a real situation.
When copying a definition into notes, keep its citation and scope language with the quotation. Removing those details can make a narrowly applicable definition look universal. A good note should allow another reader to locate the provision and understand why it was relevant to your inquiry.
