Definition
KILL carries two legally significant meanings that operate in entirely separate domains and share almost nothing but spelling.
1. To cause the death of a living being. In criminal and tort law, "kill" denotes the act of causing death, whether human or animal. As applied to human beings, it is the root act underlying homicide in all its forms — murder, manslaughter, and justifiable or excusable killing. The word itself is value-neutral at the definitional level: it describes the causal fact of death without specifying the mental state or legal consequence. Whether a killing is criminal depends on attendant circumstances — intent, premeditation, provocation, legal justification — not on the word itself.
2. A creek, channel, or small stream. In New York property and water law, "kill" is a geographic and legal term of Dutch origin denoting a watercourse: specifically, a creek, inlet, channel, or the bed of a river. The term is embedded in place names throughout the Hudson Valley and surrounding regions (Catskill, Peekskill, Schuylkill) and appears in deeds, grants, boundary descriptions, and riparian rights instruments drawn under the Dutch colonial period and carried forward into New York common law.

Common Language
Modern common usage (Wiktionary): To put to death; to extinguish the life of. Also broadly: to stop, terminate, disable, overwhelm, or cause pain to.
Historical common usage (Webster's 1913): Listed only as an obsolete form of "kiln." The homicide meaning, then fully dominant in ordinary speech, was apparently treated as too self-evident to require entry.
The gap here is definitional splitting, not definitional drift. The Wiktionary entry captures the familiar death-causing sense but has no trace of the watercourse meaning. A researcher encountering "kill" in a nineteenth-century New York deed or boundary survey must recognize that the term may describe geography, not violence — a distinction that can determine the scope of riparian rights or property boundaries.

Common Confusion
Do not conflate "kill" (the act causing death) with "murder" or "manslaughter." Killing is the factual predicate; murder and manslaughter are legal conclusions that layer intent and circumstances onto that predicate. A lawful execution, a justified act of self-defense, and a premeditated homicide are all killings. Only one is murder. Similarly, do not read "kill" in historical New York instruments through a modern default lens — the watercourse sense is not metaphorical or archaic slang; it is technical geographic vocabulary with legal consequences for title and water rights.

Why It Matters in Research
For criminal law researchers: The word "kill" in statutes and indictments is a term of causation, not culpability. Early American criminal codes often used "kill," "slay," and "murder" interchangeably in ways that courts later had to untangle. When reading historical indictment forms or charging language, track whether the instrument uses "kill" as the operative verb or as a synonym for murder — the distinction affects how courts interpreted the mental state requirement. Modern codes tend to reserve "kill" for the causal element and specify mens rea separately.
For property and water law researchers: The New York watercourse sense of "kill" is invisible to most modern legal databases and search tools. A full-text search for "kill" in digitized New York colonial grants, Dutch land patents, or Hudson Valley boundary deeds will return the geographic term without flagging it as such. Researchers working on riparian rights, boundary disputes, or title chains in the Hudson Valley, Long Island, or New Jersey regions should treat every instance of "kill" as presumptively geographic until context rules it out.
For constitutional and international law researchers: The targeted killing context — drone strikes, executive action against designated threats — has generated a distinct body of scholarship and litigation that uses "killing" and "targeted killing" as terms of art. The constitutional dimensions (due process, separation of powers, war powers) are substantially different from domestic homicide law. The encyclopedia entry on Drone Strikes and Targeted Killing is the relevant corpus connection.

Historical Dictionary Support
Burrill's Law Dictionary is the sole historical source in the Law Mind corpus for this term and it addresses only the watercourse meaning, not the homicide meaning. Burrill traces "kill" to Dutch origin, defines it as a channel or bed of a river and hence the river or stream itself, and cites 1 Comstock's Reports 107 as authority — a New York Court of Appeals decision that treated the term as a recognized geographic designation in property law. This entry reflects a choice: Burrill apparently regarded the death-causing sense of "kill" as too deeply ordinary to require legal definition, while the Dutch watercourse term needed explication precisely because it was regional and unfamiliar to lawyers outside New York.
The absence of the homicide meaning from Burrill is itself instructive. Nineteenth-century legal dictionaries frequently omitted terms whose meaning in law tracked common understanding closely enough. The criminal law sense of "kill" was defined, in practice, by the surrounding doctrine of homicide rather than by the word itself.
No other historical dictionary in the current corpus covers this term. Researchers seeking historical treatment of killing in the criminal law sense should consult homicide, murder, and manslaughter entries across the shelf sources.

Jurisdictional Note
The watercourse meaning of "kill" is substantially confined to New York and, to a lesser extent, New Jersey and Pennsylvania — regions of Dutch colonial settlement. It has no legal significance in other American jurisdictions. The homicide meaning is universal across common law jurisdictions, though the statutory frameworks built on top of that factual predicate vary considerably by state and country.
