Definition
FAIR carries two distinct legal meanings that operate in almost entirely separate doctrinal contexts. Researchers must determine which sense governs before proceeding.
1. A fair (noun): A public commercial event — a kind of superior or expanded market — held periodically at a designated location, typically authorized by royal grant or long prescription. In English and early American law, a fair was a recognized legal institution, distinct from an ordinary market by its scale, periodicity, and the legal privileges it conferred on participants. Fairs were typically held annually or semi-annually, attracted traders from a wider geographic area, and operated under special rules governing the sale of goods, the resolution of disputes, and immunity from certain civil process during the fair's duration.
2. Fair (adjective): In modern legal usage, "fair" functions primarily as a normative standard — meaning just, impartial, equitable, or adequate under the circumstances. It appears in constitutional doctrine (fair trial, fair hearing), contract law (fair dealing), corporate law (entire fairness), consumer protection and lending statutes, and employment law. The adjective rarely carries a single fixed technical meaning; its content is typically defined by context, doctrine, and the standard of review applicable in a given area.

Common Language
Modern common usage (Wiktionary): Beautiful, of pleasing appearance; unblemished or pure; light in color; just; adequate or reasonable but not excellent; favorable to weather or a ship's course.
Historical common usage (Webster's 1913): Free from spots or imperfection; clean; pure; pleasing to the eye; handsome; of a light or clear complexion; not overcast; cloudless and pleasant.
The gap matters in two directions. First, "fair" in ordinary English carries aesthetic and meteorological meanings (fair weather, fair complexion, fair-haired) that are entirely absent from legal usage. Second, the ordinary sense of "adequate but not excellent" — as in "fair performance" — understates the legal threshold. In legal contexts, "fair" often functions as a demanding standard: "entire fairness" in corporate law, for instance, requires both fair dealing and a fair price, and courts scrutinize both rigorously. Researchers reading legal sources should not interpret "fair" as merely passable or middling.

Common Confusion
The noun and adjective senses appear in historical legal dictionaries as a single entry, which can mislead researchers. When Bouvier or Burrill define "fair," they are addressing the commercial institution — the periodic market event — not the normative standard of justice or equity. A researcher searching historical sources for doctrine on "fair dealing" or "fair value" will find little guidance under the "fair" entry; those concepts developed primarily through case law and statute, not through the institutional definition that occupied the dictionary compilers. Conversely, a researcher looking for the law of fairs and markets should not rely on modern statutory or constitutional entries that use "fair" in its adjectival sense.

/SUBTYPES
As a noun (the commercial institution):
- Statute fair: A fair held under statutory authorization, as distinguished from those held by royal grant alone.

As an adjective (normative standard):
- Fair trial: Constitutional guarantee of an impartial hearing, grounded in due process.
- Fair dealing: The obligation, arising in contracts and fiduciary relationships, to act honestly and without bad faith toward the other party.
- Fair value / Fair price: A standard used in corporate law (particularly appraisal proceedings and freeze-out mergers) to determine adequate compensation for minority shareholders.
- Fair lending: Statutory prohibition on discriminatory lending practices, enforced under federal statutes including the Equal Credit Opportunity Act and Fair Housing Act.
- Entire fairness: The heightened corporate law standard requiring a showing of both fair dealing and fair price when a controlling shareholder stands on both sides of a transaction.

Why It Matters in Research
The noun/adjective bifurcation is a persistent navigational trap. Historical dictionaries — Bouvier, Burrill, Black's 2nd — define "fair" almost exclusively as the commercial institution, reflecting the term's legal prominence in English common law. Researchers working in modern doctrine (employment law, corporate law, constitutional law, consumer finance) will find these entries largely irrelevant and should proceed directly to statutory texts, treatises, and case law organized around the specific doctrinal use: fair dealing, fair value, fair hearing, and so on.
For researchers working in English legal history or early American commercial law, the institutional meaning is directly operative. The law of fairs governed immunity from arrest during the fair period (a form of safe conduct for traders), the jurisdiction of the pie powder court (the summary merchant tribunal held at fairs), and the privileges of buying and selling without the usual market restrictions. These concepts connect to broader research on merchant law, market regulation, and the development of commercial courts.
In the modern adjectival uses, the key research challenge is that "fair" is not self-defining — courts and legislatures give it specific content in each domain. The "fair" in "fair and equitable treatment" under an investment treaty is not the same standard as "fair value" in a Delaware appraisal proceeding or "fair hearing" under administrative due process. Corpus researchers should resist treating fair as a stable, cross-contextual term.
Jurisdictional variation is significant in corporate law: what constitutes "entire fairness" is developed most thoroughly in Delaware doctrine but applied differently in other states. In employment law, the duty of good faith and fair dealing is recognized in most jurisdictions but its scope and enforcement mechanisms vary substantially.

Historical Dictionary Support
Bouvier defines a fair as "a public mart or place of buying or selling" and a "greater species of market, recurring at more distant intervals," citing Blackstone. He notes that it includes exhibitions of agricultural and mechanical products — a nod toward the 19th-century county fair, which blended commercial and civic functions. Burrill echoes this, tracing the term to the Latin feria and nundinae, and describing the fair as a larger market institution, authorized by grant or prescription. Both dictionaries treat the fair as a formal legal entity, not merely a popular event.
Rapalje and Lawrence add useful procedural detail: no fair could be held in England without royal grant or prescription, and before a patent was issued, a writ of ad quod damnum would be executed to ensure the new fair would not prejudice an existing fair or market. This reflects the crown's regulatory interest in controlling commercial geography.
Black's 2nd does not appear to supply a direct entry for "fair" in its adjectival sense through the provided excerpt; the Black's passage in the source material addresses failure of consideration under a separate headword. This is itself informative — at the time of Black's 2nd (1910), "fair" as a freestanding doctrinal term in the modern sense had not yet consolidated into dictionary-worthy doctrine. The normative uses of "fair" in constitutional and commercial contexts developed substantially through 20th-century case law and legislation.
Anderson's entry, as excerpted, addresses ex post facto law rather than "fair" directly — suggesting either a scanning or organizational artifact in the source material. Researchers should treat Anderson's contribution to this entry as limited.
Historical dictionaries collectively offer strong coverage of the fair-as-institution and essentially no coverage of fair-as-normative-standard. This gap is itself a research finding: the doctrinal elaboration of fairness as a legal standard is a modern development that postdates the classic dictionary tradition.

Jurisdictional Note
The law of fairs as a commercial institution is primarily an English common law concept and has no significant continuing legal vitality in American jurisdictions. The adjectival uses of "fair" — in constitutional, corporate, employment, and consumer finance law — vary meaningfully by jurisdiction, particularly between federal standards and state law. Delaware corporate law provides the most developed body of doctrine on entire fairness and fair value in the merger context; researchers applying these concepts in other states should verify whether local courts have adopted, modified, or rejected the Delaware framework.
