Definition
A company is an association of persons organized to carry on a common business, commercial, or industrial undertaking. The term is broad enough to encompass both incorporated and unincorporated forms of business organization, and its legal meaning depends heavily on context, jurisdiction, and era.
1. General sense. Any association of individuals united for a shared lawful purpose, whether or not formally incorporated. In this broad sense, a partnership, corporation, limited liability company, or voluntary association may each qualify as a "company."
2. Corporate or quasi-corporate sense. In modern usage, "company" most often signals an incorporated or formally organized entity — a legal person separate from its members, capable of contracting, holding property, and suing in its own name. British and Commonwealth usage especially employs "company" as the standard term for what American law calls a corporation.
3. Partnership sense (historical and residual). Historically, "company" was used to describe unincorporated associations of persons trading under a collective name. It also designated the silent or unnamed members of a firm — the "& Co." in a firm name — as distinguished from the named partners whose names appeared in the firm's title.
4. Surety and specialty companies. Specific statutory and judicial contexts have produced defined subtypes: guaranty companies, surety companies, insurance companies, holding companies, and investment companies each carry distinct regulatory meanings that deviate from the general definition.
Common Language
Modern common usage (Wiktionary): To accompany; to associate; to keep company with.
Historical common usage (Webster's 1913): Fellowship; companionship; an assemblage or association of persons, either permanent or temporary.
The common English word "company" carries a social or relational sense — people being together, accompanying one another. The legal term retains that root but transforms it into an organizational concept: persons not merely gathered but formally associated for a shared commercial purpose, with rights and obligations that may persist regardless of changes in membership. A researcher encountering "company" in older documents should not assume corporate incorporation; the word may simply mean a group of traders or partners acting jointly under a collective name.
Recognized Forms
/SUBTYPES
Joint-stock company. An unincorporated association with transferable shares, historically occupying a middle ground between partnership and corporation. A significant subject in nineteenth-century law before general incorporation statutes displaced it.
Holding company. A company organized primarily to own shares in, and control, other companies. Regulated in the banking context by the Bank Holding Company Act.
Investment company. A company whose primary business is investing in securities on behalf of shareholders. Governed in the United States by the Investment Company Act of 1940.
Surety/guaranty company. A company authorized by statute to act as a surety or guarantor for others; distinguished judicially from insurance companies in ordinary usage.
Limited liability company (LLC). A modern statutory hybrid entity that frequently carries "company" in its name but operates under a distinct legal framework separate from traditional corporations or partnerships.
Why It Matters in Research
Ambiguity across time and form is the central research hazard with this term. In sources predating general incorporation statutes — roughly pre-1850 in most American jurisdictions, and longer in others — "company" almost certainly refers to an unincorporated association, partnership, or joint-stock arrangement, not a corporation in the modern sense. Researchers projecting modern incorporated-entity assumptions backward will misread the legal relationships involved.
The "& Co." problem is a recurring trap in partnership law sources. When older cases or treatises refer to the liability or identity of the "company" portion of a firm name, they mean the unnamed partners or associates, not a separate legal entity. Anderson's Dictionary of Law specifically flags that use of "& Co." creates a rebuttable presumption of an additional partner — a rule with direct evidentiary consequences in historical litigation.
Jurisdictional labeling diverges sharply. British sources use "company" as the standard term for incorporated entities (public company, private company, limited company) governed by Companies Acts. American sources split: corporations are typically called corporations, while "company" appears in firm names and specialty regulatory contexts. Researchers working across Anglo-American materials must anchor the term to its jurisdictional context before drawing inferences about legal form.
Regulatory subtypes require separate research tracks. "Holding company," "investment company," "insurance company," and "surety company" each trigger distinct statutory regimes. Finding the word "company" in a regulatory opinion or statute is only the starting point; identifying which subtype is at issue determines which body of law controls.
Corpus connections. The Law Mind Business Organizations & Corporate Law Encyclopedia treats investment companies and bank holding companies in dedicated entries that significantly expand on the dictionary-level definition. Researchers pursuing the regulatory dimensions of either subtype should move directly to those materials.
Historical Dictionary Support
The historical dictionaries converge on a common core: a company is an association of persons, more numerous than a typical partnership, united for a commercial or industrial purpose. Burrill states this most economically. Black's (both editions), Bouvier's, and Rapalje & Lawrence all add the refinement that "company" was conventionally distinguished from "firm" or "partnership" by size, capital, and the transferability of interests.
Bouvier's offers the most useful cautionary note, explicitly stating that "company" is not synonymous with partnership, even though every unincorporated company is a partnership in legal effect. This distinction — company as social/commercial designation, partnership as the underlying legal form — is essential for reading nineteenth-century sources accurately.
Rapalje & Lawrence contributes the clearest articulation of the transferable-share feature as a distinguishing characteristic: a company member, unlike a typical partner, could assign a share to a third party subject to the company's regulations. This points toward the joint-stock company as the historical archetype the dictionaries had principally in mind.
Anderson's Dictionary of Law focuses specifically on the "& Co." usage, treating "company" as a legal shorthand for the unnamed partner(s) in a firm. This particular meaning is almost entirely absent from modern legal usage but appears throughout nineteenth- and early twentieth-century case law on partnership liability.
What the historical sources collectively miss: they do not address the modern regulatory company — the investment company, bank holding company, or LLC — because those forms postdate them. Nor do they grapple with the full separation of legal personality that modern corporate law takes for granted. Researchers should treat the historical definitions as reliable for organizational and partnership-law questions but insufficient for any regulatory or modern corporate inquiry.
Jurisdictional Note
In the United Kingdom and most Commonwealth jurisdictions, "company" is the statutory term of art for incorporated entities formed under Companies Acts, with public and private companies as the primary classifications. In the United States, "corporation" carries that role, and "company" functions more as a commercial label than a precise legal designation — though it acquires technical meaning in specific regulatory contexts such as the Investment Company Act of 1940 and the Bank Holding Company Act.
