Definition
The mouth of a harbor; the point at which a harbor opens into a larger body of water. In legal usage, "chops" refers to the entrance or opening of a harbor, and by extension has been applied to the mouths of channels or bays. The term appears primarily in maritime and navigational statutes, notably in Massachusetts public statutes of 1882, where it defined the geographic scope of harbor-related regulations.
Common Language
Modern common usage (Wiktionary): The jaws, lips, or mouth of a person or animal; colloquially, one's skill or ability at a task, especially musical performance. Also, the area where two tidal flows meet and produce choppy water.
Historical common usage (Webster's 1913): "The jaws; also, the fleshy parts about the mouth. The sides or capes at the mouth of a river, channel, harbor, or bay; as, the chops of the English Channel."
The common usage in Webster's 1913 is actually the bridge between legal and colloquial meaning: the geographic sense — capes or sides at the mouth of a channel — is the ancestor of the legal usage. Modern readers encountering "chops" in a legal text are unlikely to recognize the term as a geographic or nautical designation, since that sense has largely dropped from everyday English. The colloquial sense of skill or talent is entirely unrelated to the legal meaning and should not mislead research.
Why It Matters in Research
This is a narrow, statute-specific term. Researchers are unlikely to encounter "chops" as a live legal issue in contemporary materials; its significance is almost entirely historical and definitional within older maritime and harbor law sources.
The critical research trap is geographic and contextual: "chops" in a 19th-century Massachusetts statute or admiralty document means the harbor's mouth — a boundary point for jurisdictional or regulatory purposes — not any sense related to the modern colloquial meaning. A researcher reading harbor-use regulations, port authority grants, or maritime trespass statutes from this period who encounters "chops" must treat it as a term of geographic art, not as an imprecise or colorful expression.
The Webster's 1913 entry provides useful confirmation that the geographic sense of "chops" (sides or capes at the mouth of a waterway) was current in 19th-century American English, which helps explain its appearance in statutory drafting of that era. That common understanding had faded by the mid-20th century, which is why the term rarely appears in later legal materials without definition or gloss.
For corpus researchers: occurrences of "chops" in Law Mind materials should be reviewed in context. In maritime, harbor, or admiralty documents, it is almost certainly this geographic term. In any other context — particularly 20th century or later — it may be common language or slang and carries no legal freight.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) and Bouvier's Law Dictionary are in complete agreement: "chops" means the mouth of a harbor, each citing Massachusetts Public Statutes of 1882, page 1288, as the authoritative statutory source. The uniformity across all three dictionaries, and the shared citation to a single statutory reference, indicates this was a term of limited but precise legal use — drawn into legal dictionaries because it appeared in an operative statute, not because it had broad common law history.
None of the historical sources explore the term beyond this one-line definition, and none trace its origins in maritime custom or admiralty practice. Bouvier and both editions of Black offer no additional analytical commentary. Researchers should not read depth into the entry that the sources do not supply. The term's legal career appears to have been brief, statute-bound, and geographically specific to Massachusetts harbor law of the late 19th century.
Jurisdictional Note
The documented legal usage derives from Massachusetts statute. Whether other states or admiralty courts employed "chops" as a term of art in harbor regulation is not established by the historical dictionary sources. Caution is warranted before assuming the definition travels across jurisdictions.
