Definition
A Latin term from the civil law meaning nearness of dwelling, neighborhood, or a neighboring place. In legal usage, vicinia refers to the locality or district from which jurors were historically drawn, grounded in the principle that those who resided near the scene of a dispute or transaction were best positioned to know the relevant facts. The concept underlies the common law doctrine of vicinage — the right to trial by a jury of persons from the neighborhood or county where the alleged offense or matter arose.
The term carries two related but distinct senses in legal sources:
1. Geographical: The physical neighborhood or surrounding locality, as a territorial reference point.
2. Procedural: The body of neighbors summoned to give evidence or render a verdict based on their local knowledge, functioning as a precursor to the modern jury panel drawn from a defined district.

Common Language
Modern common usage (Wiktionary): Not a standard entry in modern English dictionaries; vicinia is treated as a Latin or archaic term with no common English counterpart in active use.
Historical common usage (Webster's 1913): Not independently listed; the cognate term "vicinity" is defined as nearness of place; a neighboring or surrounding district.
The legal significance of vicinia exceeds what the word "vicinity" conveys today. Modern English treats vicinity as a loose spatial reference. In its legal sense, vicinia designated a defined jurisdictional community — a body of neighbors with firsthand knowledge whose collective testimony or verdict carried institutional weight. The geographic idea is preserved in modern usage; the procedural and evidentiary dimensions are not.

Common Confusion
VICINIA vs. VICINAGE: These terms are closely related and often treated as synonymous in secondary sources, but they are not identical. Vicinia is the Latin root, describing the neighborhood or locality as a place. Vicinage is the anglicized derivative, used specifically in the common law context of jury composition and, later, as a constitutional term in the Sixth Amendment's guarantee of trial by an impartial jury of the state and district where the crime was committed. Researchers encountering vicinia in early sources should not assume the modern constitutional meaning of vicinage applies — that doctrinal development came later and through a distinct line of English and American authority.
VICINIA vs. VICINITAS: Some civil law texts distinguish between vicinia (the neighborhood itself) and vicinitas (the relation of being neighbors, or neighborliness as a legal condition giving rise to obligations). The distinction matters in Roman law contexts but is rarely observed in English legal dictionaries or common law sources.

Why It Matters in Research
Vicinia is primarily a term of historical and Roman law significance. Researchers working in medieval English legal records, early common law treatises, or civil law sources will encounter it as a foundational concept behind jury selection and local knowledge requirements.
Key navigational points:
First, the term appears inconsistently across historical dictionaries. Burrill's entry is truncated — the printed text cuts off mid-sentence, a common artifact of early legal dictionary publication and page-scanning. Researchers should not treat Burrill's partial entry as a complete definition and should cross-check with civil law sources and Cowell's Interpreter or Spelman's Glossarium for fuller treatment.
Second, vicinia connects directly to the historical jury as a body of witnesses, not merely fact-finders. Early juries were drawn from the vicinia precisely because jurors were expected to know local conditions, parties, and events. This differs fundamentally from the modern conception of jurors as impartial strangers to the dispute. Researchers tracing the evolution of jury theory will find vicinia central to the earlier model.
Third, the transition from vicinia (civil law neighborhood) to vicinage (common law jury right) to the Sixth Amendment's district requirement reflects a long doctrinal evolution. Materials using vicinia are almost certainly operating in the older civil law or early common law register, not in the constitutional law register. Conflating the two in historical research produces anachronistic readings.
Fourth, in property and nuisance law, vicinia surfaces in early common law doctrine governing obligations between neighbors — particularly regarding support of land, watercourses, and use of common resources. This usage is distinct from the jury-related sense and should be treated separately when encountered in that context.

Historical Dictionary Support
Burrill's Law Dictionary defines vicinia as a term from the civil law meaning "nearness of dwelling; neighborhood; a neighboring place" and notes its distinction from confinia (boundaries or borders). The entry, though fragmentary in surviving printed form, situates vicinia squarely within the Roman law tradition of territorial proximity rather than boundary demarcation — vicinia describing the lived community of neighbors, confinia describing the line separating them.
Burrill's is the primary surviving common law dictionary treatment. The entry's truncation reflects a printing artifact rather than editorial judgment, and researchers should not interpret the brevity as indicating the term's insignificance. In Cowell's Interpreter (1607) and Spelman's Glossarium Archaiologicum (1687), vicinia receives more extended treatment in connection with early jury theory and the summons of neighbors to attest local facts — sources that Law Mind researchers should consult when Burrill's falls short.
No significant divergence exists among historical sources on the core meaning. The point of variation is in application: civil law sources use vicinia as a descriptive geographic term; early English common law sources extend it into procedural doctrine regarding who may serve on a jury or inquest. Modern legal dictionaries largely abandon the Latin term in favor of vicinage, leaving vicinia to appear chiefly in historical and comparative law contexts.

Jurisdictional Note
Vicinia as a term of art is not operative in modern American or English statutory law, which uses vicinage or venue. Its relevance is confined to historical common law materials, Roman and civil law sources, and early English statutes — including references in the Statutes of Westminster (13th century) and associated commentary — where the Latin form was standard.
