Definition
To engage, in legal contexts, carries several related but distinct meanings depending on the instrument or proceeding at issue:
1. To bind by contract or obligation. A party who "engages" to perform an act undertakes a legally enforceable promise to do so. The word functions as a term of commitment — equivalent to covenant, promise, or undertake — and signals the creation of a duty.
2. To enter into or carry on a business, occupation, or activity. Statutes, bylaws, licensing codes, and restrictive covenants frequently prohibit or condition a person's right to "engage in" a trade, profession, or practice. In this sense, engage means sustained, active participation or involvement — not merely a single transaction.
3. To employ or retain. A principal who engages an agent, contractor, or professional secures their services, typically by agreement. This usage appears in agency law, employment instruments, and professional retainer arrangements.
4. To participate or take part. Regulatory and administrative contexts use engage broadly to describe participation in a regulated activity, such as engaging in the business of banking, securities dealing, or insurance.

Common Language
Modern common usage (Wiktionary): To interact socially; to draw into conversation; to hold the attention of; to enter into conflict with an enemy; to enter into battle; to attract or please.
Historical common usage (Webster's 1913): To put under pledge; to bind by contract or promise; to gain for service; to enlist; to gain over and attract.
Editorial note: The common meaning of engage is broad and situational — it can mean anything from social interaction to military combat. The legal meaning is narrower and more consequential: when engage appears in a contract, bylaw, or statute, it signals an obligation, a restriction, or a defined scope of activity. A reader applying the ordinary conversational sense risks missing the binding or participatory weight the word carries in legal instruments.

Common Confusion
The central interpretive problem with engage is scope. Courts have had to determine whether "engaging in" an occupation or business requires active, hands-on participation, or whether passive involvement — such as holding a partnership interest without managing operations — suffices. Bouvier's flags exactly this tension: in the context of a life insurance association bylaw, engage in an occupation was held to cover a silent partner who took no active role. Researchers should not assume that "engage" in a restrictive covenant or bylaw requires personal, direct activity. The word has been construed to reach indirect participation.
Engage is also sometimes used interchangeably with employ in older instruments, but the two are not synonymous: to employ suggests a hierarchical, wage-based relationship, while to engage is broader and covers independent contractors, agents, and retained professionals.

Why It Matters in Research
For corpus researchers, engage is a high-frequency function word that carries variable legal weight depending entirely on context. Three traps are worth flagging:
First, in restrictive covenants and occupational bylaws, the scope of engage is almost always litigated. Historical sources — including Bouvier's — show courts reading the term broadly, to include partnership interests and passive roles. Modern employment and licensing cases continue to dispute whether engage requires active participation. Do not read historical instruments with a narrow construction assumption.
Second, engage appears in both promissory and descriptive roles within the same document. "The party engages to deliver" creates a duty; "the party is engaged in manufacturing" describes a state of affairs. Conflating these roles produces misreading of obligations.
Third, in securities, banking, and insurance regulatory materials — particularly those predating the mid-twentieth century reorganization of federal financial regulation — "engaged in the business of" is a term of art with specific definitional consequences. Whether a party is engaged in the business of dealing, advising, or underwriting determines regulatory jurisdiction. Researchers working in this corpus should trace how each regulatory regime defined the phrase, because the standard is not uniform across statutes or agencies.

Historical Dictionary Support
Bouvier's defines engage as "to embark; to take a part; to devote attention and effort," and separately notes the partnership interpretation from New York authority. This entry is brief but practically oriented — Bouvier's flags the coverage dispute directly rather than offering an abstract definition.
Webster's 1913 preserves the older, pledge-centered sense: to engage meant fundamentally to bind by word, oath, or contract. This promissory core is older than the occupational usage and remains visible in instruments that use engage as a synonym for covenant or undertake.
What the historical dictionaries collectively miss is the regulatory dimension — the use of engage as a jurisdictional trigger in licensing and financial regulation. This usage developed substantially in the late nineteenth and twentieth centuries and is not adequately captured in sources of Bouvier's vintage. Researchers working in regulatory or administrative law contexts should treat historical dictionary entries as a starting point only.

Jurisdictional Note
Interpretation of "engage in" as covering passive business interests (such as silent partnerships) has been applied in New York and other jurisdictions with commercial bylaw disputes, but courts in other contexts have required active participation. Statutory uses of "engaged in the business of" in federal regulatory law carry their own definitional frameworks independent of common-law contract interpretation.
