latrocinium

Larceny comes through Anglo-French larcin and Old French larcin (theft, robbery), from Latin latrocinium (robbery, banditry, mercenary service), from latro (robber, bandit, hired soldier, mercenary). The Latin latro is a borrowing from Greek λάτρον (latron, pay, hire), related to λατρεύω (latreuō, to serve for pay, to worship) — making the original sense of latro something close to 'one who works for hire.' The semantic journey from 'hired soldier' to 'bandit' to 'thief' reflects a historical reality of the ancient world: mercenary soldiers were a constant feature of Mediterranean warfare, and the line between paid military service and armed robbery was often indistinct. When a mercenary's employer could not pay, or when the campaign was over, the armed man had to provision himself somehow. The latro was the armed man who took what he needed; the latrocinium was his taking.

In English common law, larceny developed as the primary property offense from the medieval period and was divided into grand larceny and petit larceny based on the value of the property stolen. Grand larceny — theft of goods above a certain value threshold — was a capital offense in medieval England; petit larceny was punishable by flogging or other lesser sanctions. The grand/petit distinction entered American law through the colonial reception of English common law and persists in modified form in many U.S. state codes, where the distinction between grand theft (a felony) and petty theft (a misdemeanor) is drawn at monetary thresholds that vary by jurisdiction. The medieval value thresholds have been updated, but the two-tier structure is continuous.

The law of larceny required a highly specific set of elements: a trespassory taking and carrying away of personal property of another with intent to permanently deprive. Each of these elements was defined with considerable precision by the common law courts, and cases turned on technical questions — whether the taking was 'trespassory' (against the owner's will), whether the carrying away ('asportation') was sufficient, whether the intent was to deprive permanently rather than temporarily. A person who borrowed a car without permission and intended to return it had not committed larceny under the strict common law definition; most jurisdictions created a separate offense of 'unauthorized use of a vehicle' to fill this gap. The precision of the common law definition of larceny generated a proliferation of specific theft offenses around its edges.

Most modern criminal codes have consolidated larceny, embezzlement, false pretenses, and other theft-related offenses into a single 'theft' statute, retaining the grand/petit distinction but shedding the technical requirements of the common law larceny definition. This consolidation reflects a reform movement in criminal law that prioritized functional definitions over historical categories: a person who takes another's property dishonestly should be guilty of theft regardless of whether the taking satisfied the precise requirements of common law larceny. The word 'larceny' survives in American law, particularly at the state level, and in colloquial usage ('it's grand larceny what they charge for parking'), but it is gradually giving way to the more general 'theft' in both statutory and popular vocabulary.
