Definition
The territorial jurisdiction of a sheriff or bailiff. In its primary sense, a bailiwick is the geographic area within which a sheriff holds authority — the county or district over which that officer exercises official power. In a secondary historical sense, it refers to a liberty or franchise jurisdiction that was carved out from the ordinary county administration: a defined precinct exempted from the county sheriff's reach, governed instead by a lord's appointed bailiff who exercised locally the same functions the under-sheriff performed countywide.
Two senses, then, operate in the sources:
1. The sheriff's bailiwick — the county itself, considered as the unit of the sheriff's operational authority.
2. The franchised bailiwick — an enclave of private jurisdictional authority, a liberty held by a lord and administered by his own bailiff, insulated from the county sheriff's writ.

Common Language
Modern common usage (Wiktionary): "One's area of expertise, interest, or authority; one's sphere of operation." Used informally to mean any domain of competence or concern — "that's outside my bailiwick."
Historical common usage (Webster's 1913): "The precincts within which a bailiff has jurisdiction; the limits of a bailiff's authority."
The gap is significant. In modern ordinary English, bailiwick has been generalized into a metaphor for any personal or professional domain. The legal meaning is territorial and jurisdictional — a physical, bounded area within which a specific officer holds delegated governmental authority. A researcher encountering the word in a legal source cannot read it as the modern colloquialism; it refers to defined geographic and administrative limits.

Why It Matters in Research
Corpus researchers should hold two distinctions in mind when reading historical sources that use this term.
First, the word appears in two very different contexts: descriptions of ordinary county administration (the sheriff's bailiwick = the county) and descriptions of franchise or liberty jurisdictions (the lord's bailiwick = an exempted precinct). These are not the same thing, and confusing them distorts understanding of how local authority was structured in English and early American law. A liberty or franchised bailiwick represents an exception to normal county governance — it is, in effect, a pocket jurisdiction that disrupts the ordinary reach of the crown's or state's local officer.
Second, the franchised bailiwick as a living institution did not survive robustly into American law. American legal sources generally use bailiwick in the simpler sense — the geographic limit of a sheriff's or constable's authority — and the feudal franchise sense fades from practical relevance after the colonial period. Researchers working with early American or colonial materials should be alert to which sense is operative.
Third, jurisdictional limits carry real procedural consequences in historical sources. Service of process by a sheriff outside his bailiwick was irregular or void; understanding the bailiwick concept is therefore necessary to reading cases and treatises about service, execution of writs, and the scope of official authority.
The modern colloquial meaning is a genuine research trap. A non-specialist reader may skim past the word as metaphor when it is in fact a technical term with direct legal consequences in the passage at hand.

Historical Dictionary Support
Bouvier's Law Dictionary draws on Blackstone's Commentaries (1 Bl. Com. 344) for the core statement that a bailiwick is the jurisdiction of a sheriff or bailiff, and on Whishaw's Lex for the franchise-jurisdiction sense. The Whishaw definition supplies the more precise feudal account: an exclusive jurisdiction exempted from county sheriff authority, with the lord's bailiff exercising locally equivalent powers.
Bouvier presents both senses without ranking them, which is editorially neutral but can leave the reader uncertain which sense a given passage employs. The Blackstone citation anchors the ordinary sheriff's-jurisdiction sense to a foundational common law source, lending it priority in general usage. The Whishaw sense is narrower and more historically specific to franchise liberties.
Neither source addresses the American trajectory of the term, which is a gap worth flagging. The franchise sense had limited American reception; the county-as-bailiwick sense carried forward into American sheriff law but was increasingly replaced by more explicit statutory language about territorial jurisdiction.

Jurisdictional Note
The franchised-bailiwick concept, involving private liberties exempt from county sheriffs, had substantially greater importance in English law than in American law. American jurisdictions generally abolished or declined to reproduce franchise liberties, so the term in American legal sources almost always refers simply to the geographic limits of a sheriff's or constable's official authority. Researchers working in English legal history or colonial American sources should be alert to both senses.
