Definition
An adjective describing conduct, intent, or purpose having the character of larceny. A larcenous act is one that constitutes or amounts to a taking and carrying away of another's property with the intent to permanently deprive. A larcenous intent or larcenous purpose is the mental state accompanying such a taking — the knowing, willful appropriation of another's goods without claim of right and with intent to convert them to one's own use or to deprive the owner entirely.
The term operates primarily as a modifier. Courts and pleadings use it to characterize specific elements: a larcenous taking identifies the act; a larcenous intent identifies the mens rea; a larcenous purpose describes the motivating design that transforms an otherwise neutral act into a criminal one.

Common Language
Modern common usage (Wiktionary): Given to larceny, tending toward thievery; also used loosely to describe legal actions or commercial dealings that seem unfair or exploitative.
Historical common usage (Webster's 1913): Having the character of larceny; also used in general English to describe persons or environments disposed toward theft — as in Sydney Smith's phrase "the larcenous and burglarious world."
The gap between common and legal meaning is modest but real. In ordinary usage, larcenous can serve as a casual pejorative — a contract term or business practice might be called larcenous simply to suggest it is unfair. In legal usage, the word is precise: it imports the specific elements of larceny (taking, carrying away, another's property, without consent, with intent to deprive). Applying larcenous loosely in a legal document risks importing those technical elements where none were intended.

Common Confusion
Larcenous is sometimes loosely equated with fraudulent or dishonest, but these are not synonyms in law. Fraud involves deception as the operative mechanism; larceny involves a trespassory taking. A transaction can be fraudulent without being larcenous, and a taking can be larcenous without involving any deception. In historical sources particularly, watch for the word being used rhetorically to mean merely wrongful or dishonest — context must confirm whether the author intends the technical legal meaning.

Why It Matters in Research
Larcenous is a term of art embedded in the doctrine of larceny, and its significance in a given source tracks directly with the evolution of larceny itself. Before the consolidation of theft offenses in the twentieth century, larceny was a precisely bounded category — distinct from embezzlement, false pretenses, and robbery — and larcenous intent was a genuine technical battleground. Whether a defendant's purpose was larcenous determined whether the crime charged was made out. Cases turned on whether a taking was accompanied by larcenous intent at the moment of taking, not later.
In modern consolidated theft statutes, the word larcenous appears less often as a term of art and more often as a descriptive adjective in judicial opinions, pleadings, and jury instructions referring back to common-law heritage. Researchers working with post-consolidation materials should check whether the jurisdiction has merged larceny into a general theft offense — in those jurisdictions, larcenous intent may be translated into the statutory language of intent to deprive rather than treated as an independent doctrinal element.
In historical sources — particularly nineteenth-century indictments, state supreme court opinions, and treatises — larcenous purpose was a live pleading issue. The distinction between a trespassory larcenous taking and a taking under a bona fide claim of right was outcome-determinative, and the word larcenous in those materials carries its full technical weight. Researchers should not read it as mere color.
Cross-corpus connections: Larcenous intent connects directly to the animus furandi doctrine (the intent to steal as an element of larceny), to discussions of claim of right as a defense, and to the carrying-away (asportation) requirement. It also surfaces in civil conversion cases, where courts sometimes distinguish larcenous takings from other unauthorized appropriations.

Historical Dictionary Support
The three source dictionaries agree on fundamentals. All three define larcenous primarily as an adjective characterizing conduct or intent as having the quality of larceny. Black's first edition is spare — larcenous taking and larcenous purpose are listed as the paradigm phrases without elaboration. Bouvier adds the formulation larcenous purpose as an intention to commit larceny, with a cross-reference to the full Larceny entry.
Black's second edition is the most substantive: it defines larcenous intent with precision — a larcenous intent exists where a person knowingly takes and carries away the goods of another without any claim or pretense of right, with intent wholly to deprive the owner or convert the goods to his own use. This formulation, drawn from Wilson v. State (Texas, 1885), reflects the classical common-law animus furandi standard and is useful as a working definition for historical research.
What the historical dictionaries do not address: the gradual obsolescence of larcenous as a term of art in jurisdictions that consolidated theft offenses, and the civil-law contexts in which the word appears (notably conversion and replevin). Researchers should not assume that the technical precision reflected in Black's second edition carries forward uniformly into twentieth- and twenty-first-century usage.

Jurisdictional Note
In jurisdictions retaining common-law larceny as a distinct offense, larcenous intent remains a live element with the classical meaning. In Model Penal Code jurisdictions and states with consolidated theft statutes, larcenous intent is typically subsumed into the statutory purpose to deprive standard and the word larcenous, where it appears, is generally understood as a historical reference rather than a term of art.
