Definition
A Latin term from old English law meaning a nuisance — specifically, a harm or annoyance caused to another's use and enjoyment of property or person. The term appears in Bracton's foundational treatise on English law and carried a technical distinction between two grades of nuisance:
1. Nocumentum damnosum: A nuisance that occasions loss or damage — that is, a harm that causes measurable, tangible injury to the complainant.
2. Nocumentum injuriosum: An injurious nuisance — a harm that violates a legal right, whether or not measurable pecuniary loss can be demonstrated.
The distinction mattered procedurally: Bracton's formulation held that only the nocumentum injuriosum was actionable. A nocumentum damnosum, while harmful in a practical sense, did not necessarily cross the threshold required to obtain a legal remedy. This bifurcation reflects a broader principle in early common law that a wrong cognizable by the courts required a violation of right (injuria), not merely the experience of harm (damnum).
Common Confusion
The nocumentum damnosum / nocumentum injuriosum distinction is easy to misread as simply "less harmful" versus "more harmful." It is not a scale of severity. The distinction is jurisprudential: damnosum speaks to material loss; injuriosum speaks to the nature of the legal wrong. A minor interference with a clear legal right (injuriosum) was actionable; substantial practical harm without an underlying legal violation (damnosum) was not. Researchers encountering either phrase in historical pleading records should resist translating them loosely as simply "a nuisance" without recovering which category was alleged.
Why It Matters in Research
This term is primarily a research artifact — it does not appear in modern legal usage, having been wholly absorbed into the English word "nuisance" and the common law doctrines developed from Bracton forward. Researchers encounter nocumentum in three contexts:
First, in reading Bracton directly (De Legibus et Consuetudinibus Angliae, fol. 221) or in works citing Bracton as authority. The term is a gateway to understanding how Bracton framed the early law of nuisance and the foundational injuria/damnum distinction that persists, in evolved form, in tort doctrine today.
Second, in historical pleading records. Medieval and early modern writs sounding in nuisance may employ nocumentum or its compounds. Understanding the damnosum/injuriosum distinction is necessary to interpret what the pleader was alleging and what remedy was being sought.
Third, in the corpus of treatises and commentaries that cite Bracton on nuisance — including Coke, who engaged heavily with Bracton, and later systematizers of common law nuisance doctrine. The Latin terminology appears as a point of historical grounding in those works even after the concept had been Anglicized.
Trap for researchers: Rapalje & Lawrence's entry for nocumentum is garbled in surviving printings, running the definition into adjacent entries without clean separation. Treat that source as confirmatory only; Black's and Burrill's provide the cleaner analytical statement.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) provides identical treatment: a concise definition of nocumentum as "nuisance," followed by the damnosum/injuriosum distinction, with the actionability rule attributed to Bract. fol. 221. This is the authoritative historical dictionary statement on the term and reflects consensus across the shelf sources.
Burrill's Law Dictionary adds the etymology (from nocere, to annoy) and likewise cites Bracton at fol. 221, confirming both the source and the two-part distinction. Burrill's entry appears in a typographically disrupted passage that runs into unrelated material — a known artifact of that dictionary's setting — but the nocumentum definition itself is intact and consistent with Black's.
Rapalje & Lawrence's entry is the least useful. The surviving text is fragbled, placing nocumentum in proximity to unrelated Roman law terminology without clean definitional separation. It confirms the term's presence in the historical legal vocabulary but adds nothing analytically.
All four sources converge on Bracton as the foundational citation. None of the historical dictionaries addresses the later development of nuisance doctrine that absorbed and superseded this Latin framework, which is expected given their function as reference tools rather than treatise-style histories.
Jurisdictional Note
Nocumentum is a term of old English common law with no independent modern jurisdictional life. Its significance for American law is purely historical: American nuisance doctrine descends from the English common law framework that Bracton's analysis helped shape, but American courts and statutes have not preserved or used the Latin terminology.
