Definition
PRACTICES, n. (plural). A succession of acts of a similar kind or in a like employment. In legal usage, the term carries several distinct meanings depending on context:
1. Repeated conduct or habitual behavior. A pattern of acts, whether by an individual, business, or institution, that recurs with sufficient regularity to be treated as characteristic. This sense appears in regulatory law (unfair trade practices, deceptive practices), evidentiary doctrine (routine practice under Rule 406), and professional discipline.
2. Professional practice. The active exercise of a licensed or regulated profession — law, medicine, accounting — particularly in phrases such as "practice of law" or "scope of practice." When used in this sense, "practices" is simply the plural or third-person form of the verb, but it carries the full regulatory weight attached to the underlying noun.
3. Corrupt or illegal practices. A recognized legal category, especially in election law and early commercial law, referring to acts that violate specific statutory prohibitions. Bouvier's cross-reference to CORRUPT PRACTICES and ILLEGAL reflects this distinct usage, which was common in 19th-century Anglo-American legislation.

Common Language
Modern common usage (Wiktionary): Simply the plural of "practice" — habits, customs, or repeated activities in any domain.
Historical common usage (Webster's 1913): Defined practice as a customary or habitual performance; also the exercise of a profession or occupation.
The gap between common and legal usage is contextual rather than definitional: in ordinary speech, "practices" is neutral. In law, the term frequently carries a normative charge — qualifying adjectives like "unfair," "deceptive," "corrupt," or "unauthorized" transform it into a term of art with statutory and regulatory consequences. Researchers must attend to those qualifiers, not the bare noun.

Common Confusion
PRACTICES vs. PRACTICE (singular): The singular "practice" most often refers to a professional occupation or to court procedure (rules of practice). The plural "practices" more commonly refers to repeated acts or a pattern of conduct subject to legal scrutiny. The distinction matters in regulatory and evidentiary contexts: Rule 406 governs the admissibility of "routine practice," and scope-of-practice disputes concern the boundaries of what a licensee may do, not their overall professional enterprise.
PRACTICES vs. CUSTOM: In common law, "custom" implies a usage so long-established and universally observed that it may have the force of law. "Practices" implies recurrence without necessarily implying legal force. Conflating the two can distort analysis in commercial law and trade usage disputes.

Why It Matters in Research
The term is a research multiplier, not a self-contained concept. Its importance in the Law Mind corpus depends entirely on what precedes it:
Regulatory and consumer law: "Unfair or deceptive acts or practices" (UDAP) is a term of art in state and federal consumer protection law. Searching for "practices" alone in statutes or agency materials will surface this category, but researchers need to recognize it as a distinct regulatory framework with its own elements, defenses, and agency enforcement history.
Evidentiary doctrine: Under Federal Rule of Evidence 406 and its state counterparts, evidence of a person's or organization's "routine practice" is admissible to prove conduct on a particular occasion. The word "practice" in this context has a specific foundational meaning — regularity and semi-automatic response — that is not obvious from the plain term. See the Civil Procedure & Evidence Encyclopedia entry for Rule 406.
Professional licensing: "Scope of practice" disputes arise when a licensee performs acts assigned by statute to a different licensed profession, or when an unlicensed person performs acts reserved to licensees. Historical sources use "practices" loosely; modern regulatory frameworks draw precise statutory lines. Research in this area moves quickly and state-by-state variation is significant.
Corrupt practices: In 19th- and early 20th-century sources — including statutes, treatises, and case law — "corrupt practices" was a recognized category in election law and commercial law. Bouvier's cross-reference is a signal: researchers in historical legal materials should follow that thread directly to the dedicated entries.
Trap for historical research: Early dictionaries treat "practices" at a high level of abstraction ("a succession of acts"). Modern legal usage has fragmented this into highly specific regulatory categories, each with its own doctrine. Do not read the historical definition backward onto modern statutes, or forward from modern doctrine onto 19th-century materials.

Historical Dictionary Support
Black's (1st and 2nd editions) and Bouvier's are in complete agreement on the core definition: a succession of acts of a similar kind or in a like employment. The uniformity is unsurprising — this is a descriptive baseline, not a contested legal concept.
Bouvier adds value by cross-referencing CORRUPT PRACTICES and ILLEGAL, signaling that the dictionary's substantive legal content on practices sits in those derived entries, not here. This is a structurally important signal for corpus researchers: when Bouvier cross-references rather than defines, the analytical weight is in the referenced entry.
What all three historical dictionaries miss: the evidentiary doctrine of routine practice (a 20th-century development), the modern regulatory category of unfair or deceptive acts or practices, and the detailed scope-of-practice frameworks created by state licensing statutes. None of these were developed when these dictionaries were compiled.

Jurisdictional Note
Scope of practice is defined and enforced at the state level; there is no uniform national standard. UDAP statutes vary significantly across states in their elements, remedies, and whether a private right of action exists. Researchers should not treat the bare term "practices" as implying any particular legal consequence without identifying the governing jurisdiction and the specific statutory or regulatory framework at issue.
