Definition
A house or establishment where travelers are received and furnished with lodging, food, and other necessaries while on their way. At common law, an inn was distinguished from other forms of hospitality by its public character: the keeper was obligated to receive all travelers who presented themselves in a fit condition and could pay, without requiring prior arrangement. This duty of universal reception distinguished the inn from a boarding house or private lodging, where the proprietor could accept or reject guests at will.
The term has been used interchangeably with tavern and hotel throughout legal history, though modern usage has largely settled on "hotel" for the underlying concept. The legal obligations of the innkeeper — including strict liability for the safety of guests' goods — attach to the establishment's function, not its label.
Common Language
Modern common usage (Wiktionary): A small hotel or lodging establishment, often in a rural or historic setting; also used as an initialism for "international nonproprietary name" in pharmaceutical contexts.
Historical common usage (Webster's 1913): "A house for the lodging and entertainment of travelers or wayfarers; a tavern; a public house; a hotel." Webster's also notes the older English sense of a town residence of a nobleman, and the specialized sense of the Inns of Court in London.
The legal definition tracks the common meaning closely in its core — a place for travelers — but adds a layer the ordinary speaker would not assume: at law, an inn carries mandatory admission obligations and heightened liability for guest property that no ordinary commercial establishment bears. A modern traveler calling a roadside motel an "inn" does not realize they are invoking a category with centuries of strict common-law duties attached.
Common Confusion
Inn vs. Boarding House or Lodging House: These are legally distinct. A boarding house serves regular, contracted guests; an inn serves transient travelers. The distinction matters because innkeeper liability — including the strict common-law rule making the keeper an insurer of guests' goods — applies only to true inns. Courts have repeatedly refused to extend innkeeper duties to boarding houses or restaurants that lack the transient-traveler character.
Inn vs. Tavern: Historically used as synonyms in many jurisdictions, and Black's explicitly treats them as interchangeable. But in some statutory contexts, "tavern" carries licensing implications related to the sale of alcohol that "inn" does not, and the two terms may be defined differently by the same legislature for different regulatory purposes. Do not assume synonymy when reading older statutes.
Inn vs. Inns of Court: Webster's 1913 flags the English usage of "inn" for the collegiate societies of lawyers in London (Gray's Inn, Lincoln's Inn, etc.). These are wholly distinct institutions governed by their own traditions and regulations. The word is etymologically shared but legally unrelated. Researchers in English legal history will encounter both uses and must distinguish them by context.
Why It Matters in Research
The primary research value of this term lies in innkeeper liability doctrine, which is one of the oldest strict-liability regimes in the common law. A researcher tracing the development of strict liability, or comparing it to modern products liability, will find inn cases a critical historical thread.
Jurisdictional variation in statutory definitions creates a significant trap. Many states passed innkeeper statutes in the nineteenth and early twentieth centuries that modified or capped the common-law strict liability for guest goods — sometimes drastically. These statutes often turn on whether an establishment qualifies as an "inn" under the statute's own definition, which may or may not match the common-law test. The statutory definition controls for liability-limitation purposes; the common-law definition may still control for other purposes in the same jurisdiction.
Older sources — particularly pre-twentieth century reporters — use inn, tavern, hotel, and public house interchangeably. A researcher indexing cases by term will miss relevant authority if searching only one label. Cross-searching all four is necessary for comprehensive coverage.
The mandatory reception duty (the obligation to admit all travelers) is doctrinally important beyond innkeeper law: it is an early common-law precursor to public accommodation obligations and appears in historical discussions of antidiscrimination principles. Researchers working on civil rights history or public accommodation doctrine should trace this lineage through innkeeper cases.
Bouvier's note that "a coffee-house or a mere eating-house is not an inn" was a live distinction in nineteenth-century litigation. Establishments that served food but provided no lodging, or that served only regular customers, were frequently litigated on the boundary. Historical case law on this boundary can be dense and jurisdiction-specific.
Historical Dictionary Support
The historical dictionaries converge on the core definition without meaningful disagreement: an inn is a public house furnishing travelers with lodging and necessaries, with a duty of universal reception. Burrill, Bouvier, and both editions of Black's share the same foundational description, all tracing to the same authority (3 B. & Ald. 283).
Bouvier adds the useful negative — that a coffee-house or eating-house is not an inn — and conditions inn status on provision for the "essential needs of a traveller," a functional test that courts applied when the label was disputed.
Black's (1st ed.) explicitly states that under Georgia's 1882 code, the term "inn" includes all taverns, hotels, and houses of public general entertainment, illustrating how statutory definitions expanded the common-law category for regulatory purposes.
Burrill notes the New York rule treating "inn" and "tavern" as synonymous, citing 3 Hill's R. 150 and Kent's Commentaries — a useful pointer for researchers working in nineteenth-century New York commercial law.
The Rapalje & Lawrence and Anderson's entries provided are fragmentary and do not add substantively to the definition beyond pointing toward innkeeper responsibility doctrine.
What the historical dictionaries collectively underemphasize: the procedural and evidentiary dimensions of innkeeper liability litigation, including the guest's burden of establishing that the relationship was one of inn-guest (not boarder-lodger) before strict liability attached. This is a gap researchers must fill through case law rather than dictionary sources.
Jurisdictional Note
Most U.S. jurisdictions have enacted statutes modifying the common-law strict liability of innkeepers, typically conditioning liability limitation on the innkeeper posting notice and providing a safe for valuables. These statutes frequently define "inn" or "hotel" for their own purposes, and the statutory definition may be narrower or broader than the common-law category. English law developed parallel but distinct rules, and Canadian provinces vary further. Researchers should not assume that common-law innkeeper doctrine applies unmodified in any modern U.S. jurisdiction.
