Definition
Lascivious lewdness is a common law criminal offense consisting of lewd and lascivious conduct performed openly or with sufficient publicity that it offends public morals. The defining characteristic is not merely the nature of the act but its open, public quality — the offense is directed at conduct that intrudes upon the public sphere rather than private immorality concealed from others.
The term is sometimes rendered as "open and lascivious lewdness" in older authorities, with the adjective "open" doing essential work: a secret act of the same character, however morally condemned, does not constitute this particular offense. The offense is grounded in the common law doctrine of contra bonos mores — acts against good morals — and was historically cognizable as a common law misdemeanor without the need for a specific statute.
Lascivious lewdness should be distinguished from lascivious cohabitation, which is a separate offense requiring two elements: lewd and lascivious intercourse and the parties living together. Lascivious lewdness does not require cohabitation; it requires publicity.

Common Language
Modern common usage (Wiktionary): "Lascivious" means feeling or revealing an overt desire for sexual activity; inclined to lustfulness. "Lewd" means crude and offensive in a sexual way; indecent.
Historical common usage (Webster's 1913): "Lascivious" — wanton; lewd; lustful. "Lewd" — given to the indulgence of lust; lustful; licentious.
The pairing of these two terms in legal usage is not mere redundancy. As a legal term of art, "lascivious lewdness" describes a specific public-facing offense. The common language treats the words as near-synonyms; the legal usage deploys them together to define a compound offense where the public or open character of the conduct is the essential element, not simply the nature of the act itself. A researcher who reads only the common meanings of the component words will miss the offense's structural requirement of publicity.

Common Confusion
Lascivious lewdness is frequently conflated with lascivious cohabitation, but they are distinct offenses. Lascivious cohabitation requires proof that parties lived together and engaged in lewd and lascivious intercourse — courts have required both elements, and a lawful domestic relationship (such as master and servant) negates the offense. Lascivious lewdness, by contrast, requires open or public conduct but not cohabitation. Researchers encountering indictments or case law must identify which offense is charged, as the elements, defenses, and evidentiary requirements differ.
The terms "open lewdness," "open and lascivious conduct," and "lascivious lewdness" appear interchangeably in some jurisdictions and distinctly in others. Do not assume equivalence without checking the specific statute or precedent at issue.

Why It Matters in Research
This term presents several navigational challenges for corpus researchers.
First, the offense exists at the intersection of common law and statutory law. Many 19th and early 20th century prosecutions were brought under common law authority or early catch-all morals statutes, not specific "lascivious lewdness" provisions. Researchers searching for the term in statutory indices may miss prosecutions catalogued under "open lewdness," "public indecency," "contra bonos mores," or generic morals offenses.
Second, the publicity requirement is the analytical pivot. Historical sources sometimes describe the offense without making this requirement explicit, leading researchers to treat lascivious lewdness as equivalent to any lewd act. Bouvier's is explicit that "the specific characterization of the offence is the openness and publicity of the act as distinct from a secret act." Keep this distinction in view when reading case digests that do not reproduce this nuance.
Third, lascivious lewdness is an umbrella concept that historically absorbed conduct now regulated under specific modern categories — indecent exposure, public lewdness, sexual battery, obscenity. When researching modern statutory equivalents, trace how the jurisdiction's legislature replaced (or failed to replace) common law morals offenses with defined statutory crimes.
Fourth, the overlap with lascivious cohabitation in primary source digests creates index confusion. Bouvier's treats them as distinct offenses, but some state reporters and treatise indexes group them together. Verify the precise charge before drawing conclusions from secondary source discussions.

Historical Dictionary Support
Bouvier's Law Dictionary is the principal historical authority here and provides the clearest doctrinal framing available from the shelf sources. Bouvier's explicitly identifies the offense as "lewd and lascivious conduct in public, or at least practised with such publicity as to be punishable as contra bonos mores," crediting McClain's Criminal Law for the specific characterization. The emphasis on openness as the distinguishing element is Bouvier's most useful analytical contribution.
Bouvier's also carefully separates lascivious lewdness from lascivious cohabitation, noting that the cohabitation offense requires both living together and lewd intercourse — and that a lawful domestic relationship negates the offense — while lewdness turns on public conduct.
What Bouvier's does not provide is a worked-out modern equivalent or a survey of how state legislatures codified or displaced these common law offenses. The historical dictionary entries reflect late 19th and early 20th century doctrine and are silent on the significant wave of statutory reform that followed. Researchers should treat Bouvier's as a reliable map of the common law baseline but not as a guide to any specific jurisdiction's current law.

Jurisdictional Note
Lascivious lewdness as a freestanding common law offense has been displaced in most jurisdictions by specific statutory crimes such as public lewdness, indecent exposure, or sexual misconduct. Some states retain "lewd and lascivious" as a statutory term of art, but its scope and elements vary significantly. Historical prosecutions under this label cluster in Southern and Eastern states in the period covered by the Bouvier's sources; Western states often codified conduct earlier and under different terminology.
