Definition
In Roman and civil law, an aleator is a gambler or gamester — specifically, a person who plays games of chance or hazard for money. The term is a Latin noun derived from alea (a game of chance, or the die used in such games) and appears in the Digest and Code of Justinian as a legal classification carrying defined civil consequences. The aleator was not merely a social designation but a legal status that affected a person's standing in Roman law, particularly in relation to the recovery of gambling losses and the enforceability of gaming transactions.
Common Language
Modern common usage (Wiktionary): Not in general modern English use; survives in technical, historical, and musicological contexts (the adjective "aleatory" meaning dependent on chance is the more familiar modern derivative).
Historical common usage (Webster's 1913): Webster's 1913 does not carry a primary entry for aleator as an English word, reflecting its status as a term that remained within legal Latin rather than entering general English vocabulary.
Editorial note: Because aleator never fully naturalized into common English, there is no gap between legal and common meaning to navigate — there is simply no common meaning. Researchers encountering the term outside legal Latin sources are almost certainly reading a legal or scholarly text, and the civil law definition applies without qualification.
Why It Matters in Research
Aleator is a term of Roman civil law that rarely appears in American or English common law sources. Researchers will encounter it almost exclusively in three contexts: (1) treatises and digests engaging directly with Roman or civil law sources, particularly the Digest (11.5, De aleatoribus) and the Code of Justinian (3.43); (2) early American and English legal dictionaries that systematically catalogued Latin terms from the civil law tradition; and (3) scholarship on the history of gaming law tracing the lineage of modern gambling regulations back to Roman prohibitions.
The practical trap for corpus researchers is assuming that aleator has a living common law analog. It does not. English common law developed its own vocabulary for gaming and wagering (see WAGERING CONTRACT, GAMING) largely independent of the Roman classification. When Black's or Burrill's cites Dig. 11, 5 and Cod. 3, 43, they are pointing to genuine Roman sources, not transplanting those sources into Anglo-American doctrine. A researcher looking for the legal consequences of being an aleator in a common law jurisdiction will not find them — those consequences remained Roman.
The related term ALEA is the more architecturally significant entry in most civil law dictionaries; aleator is derivative and definitionally dependent on it. Research into the civil law treatment of gaming should begin with alea and the relevant Digest title before moving to aleator as a personal legal classification.
Historical Dictionary Support
Black's (1st ed.), Black's (2nd ed.), and Burrill's Law Dictionary are in complete agreement: all three define aleator identically as a Latin civil law term for a gamester or player of games of hazard, all three derive it from alea, and all three cite the same two Roman law sources — Digest 11.5 and Code 3.43. The uniformity is itself informative: these dictionaries are not synthesizing a developing doctrine but faithfully transmitting a fixed Roman classification. There is no divergence to flag and no evolution to trace across editions.
What the historical dictionaries do not provide is the substantive civil law content of those Digest and Code titles — namely, the rules governing recovery of gambling losses, the praetorian remedies available to those who lost money to an aleator, and the social infamy (infamia) that Roman law attached to professional gaming. Researchers who need the legal consequences, not just the label, must go to the primary Roman sources or to civil law treatises rather than stopping at Black's or Burrill's definitions.
