Definition
Ebriety is an archaic legal term for drunkenness or alcoholic intoxication. In criminal law and medical jurisprudence, it denotes the state of being under the influence of alcohol to a degree recognized as legally significant — whether as a condition affecting criminal responsibility, competency, testamentary capacity, or the validity of a contract or other legal act.
The term is largely obsolete in modern legal usage, having been displaced by intoxication, inebriation, and related statutory language. It appears most often in nineteenth-century American and English legal materials.

Common Language
Modern common usage (Wiktionary): The state of intoxication or drunkenness; an instance of being drunk.
Historical common usage (Webster's 1913): Drunkenness; intoxication by spirituous liquors; inebriety. "Ruinous ebriety." — Cowper.
The common and legal meanings of ebriety are essentially coextensive: both denote alcoholic drunkenness. The legal interest lies not in definitional divergence but in the specific doctrinal contexts in which courts invoked the term — particularly criminal mitigation, incapacity defenses, and medical-jurisprudence testimony — where proof of ebriety carried precise legal consequences beyond the ordinary social fact of being drunk.

Common Confusion
EBRIETY / INEBRIETY / INTOXICATION: These three terms overlap substantially in historical legal materials and were often used without distinction. Inebriety appears more frequently in late-nineteenth-century reform and medical literature, particularly in discussions of alcoholism as a disease, while ebriety tends to appear in older common-law and criminal-law contexts. Intoxication became the dominant legal term in the twentieth century and is the standard word in modern statutes and case law. When reading historical sources, treat all three as potentially referring to the same factual condition unless the author expressly distinguishes them.

Why It Matters in Research
Researchers working in nineteenth-century American case law, treatises on medical jurisprudence, or early criminal law materials will encounter ebriety as a standard term where modern sources would say intoxication or drunkenness. The shift in vocabulary is not merely stylistic: older courts and treatise writers sometimes distinguished ebriety, inebriety, and intoxication with some precision, and the applicable legal standard — for example, whether a degree of ebriety short of complete incapacity could reduce culpability or void a contract — varied by jurisdiction and context.
Be alert to the following when searching the Law Mind corpus:
First, ebriety is a search term that will surface in criminal-law materials addressing diminished capacity, insanity defenses built on chronic alcoholism, and homicide cases where voluntary intoxication was pleaded. It also appears in probate and contract cases contesting capacity.
Second, medical-jurisprudence treatises of the period treat ebriety as a clinical as well as legal category, distinguishing acute intoxication from chronic alcoholism (sometimes called dipsomania or inebriety as a disease). Researchers should not assume ebriety in a medical-jurisprudence context maps cleanly onto the modern voluntary-intoxication doctrine.
Third, because the term is archaic, its absence from a modern index or digest does not mean the underlying doctrine is absent — it will simply appear under intoxication, incapacity, or competency headings in later materials.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) defines ebriety tersely as drunkenness and alcoholic intoxication in the context of criminal law and medical jurisprudence, citing Commonwealth v. Whitney, 11 Cush. (Mass.) 479. The brevity of Black's treatment reflects that the term was already receding from active legal vocabulary by the time of that edition; it is defined but not elaborated.
Webster's 1913 and the legal dictionaries are in full agreement on the core meaning. The Webster's entry adds literary register — Cowper's "ruinous ebriety" — confirming the word was used in educated general discourse as well as legal writing throughout the nineteenth century.
No historical dictionary surveyed draws a technical distinction between ebriety and inebriety; the terms appear to have been used interchangeably. Where nuance existed, it was in context (acute episode versus habitual condition) rather than in the terms themselves. Historical sources are largely silent on any gradations within ebriety, which is a gap researchers should be aware of when comparing nineteenth-century legal reasoning to the more tiered modern frameworks for intoxication defenses.
