Definition
In Roman and civil law, frumentum denotes grain — specifically, that which grows in an ear. The term was used in classical Roman legal texts to describe cereal crops as a category of property and, more broadly, as a subject of commercial, testamentary, and administrative regulation. It encompasses what modern usage would call grain crops generally, including wheat, barley, and similar staple cereals harvested from the stalk.
The term appears most directly in Digest 50.16.77, a title of the Corpus Juris Civilis devoted to the meaning of words and phrases (De verborum significatione), confirming frumentum as a technical classifier within Roman property and obligations law rather than a colloquial term.
Common Language
Modern common usage (Wiktionary): Frumentum is the Latin word for grain or corn; in general use it refers to cereal grain, particularly as a staple food commodity.
Historical common usage (Webster's 1913): Not separately defined; subsumed under Latin grain terminology without legal distinction.
Editorial note: The gap between ordinary and legal usage here is not one of opposed meanings but of register. In common Latin, frumentum is simply grain. In the civil law, its significance lies in classification — determining which legal rules applied to a given commodity, how it figured in leases, legacies, and public distributions, and how it was distinguished from other agricultural produce. The legal question was never what the word meant in the abstract, but which things the law treated as falling within it.
Common Confusion
Frumentum is sometimes conflated in historical research with fructus, the broader Roman law category of fruits or produce generally. The distinction matters: fructus encompasses all natural and industrial yield of a thing (including grain), while frumentum is the narrower commodity term referring specifically to grain crops. Burrill's entry gestures toward this by placing frumentum in proximity to fructus industriales, but the two concepts operate at different levels of generality. A researcher reading a civil law text on legacies or usufruct should not treat frumentum and fructus as interchangeable.
Why It Matters in Research
Frumentum is a term of Roman law that migrated into early modern common law and civil law scholarship primarily through citation to the Digest. For Law Mind corpus researchers, several navigational points apply.
First, the term appears almost exclusively in Latin-language source material or in English treatises drawing directly on Roman law. Researchers working in post-medieval English common law sources will rarely encounter frumentum as an operative legal term; its appearance in common law dictionaries reflects the scholarly habit of importing Roman vocabulary for classification purposes, not its functional use in English courts.
Second, the Digest citation (50.16.77) is consistent across all five source dictionaries in this corpus. This uniformity is itself informative: it signals that the compilers were reproducing a standard reference point rather than synthesizing independent analysis. Researchers should treat the dictionary entries as signposts to the primary Roman source, not as independent glosses.
Third, frumentum has historical significance beyond private law. In Roman public law and administrative history, grain supply (annona) was a major state concern, and frumentum was central to the vocabulary of public grain distributions, military provisioning, and provincial taxation. Law Mind entries touching Roman public law, provincial administration, or military law may use frumentum in senses that extend beyond the private-law commodity definition given in these dictionaries.
Fourth, researchers in agricultural lease history (locatio conductio of agricultural land) or legacy law (legata) in civil law jurisdictions will find frumentum appearing as a contested classificatory term — whether a bequest of "the grain" passes standing crops, harvested grain, or both was a question the Roman jurists addressed, and early modern civil law commentators carried the debate forward.
Historical Dictionary Support
All five source dictionaries give essentially the same entry: grain, that which grows in an ear, with citation to Digest 50.16.77. The uniformity across Black's (both editions), Rapalje & Lawrence, Burrill, and Bouvier indicates this is a received definition transmitted from the Roman sources without significant independent elaboration.
Burrill is the most informative, placing frumentum in textual proximity to fructus industriales and hinting at the classificatory relationship between grain as a commodity and the broader category of industrial fruits. This juxtaposition is useful to researchers but appears to reflect editorial arrangement rather than a substantive gloss on frumentum itself.
None of the historical dictionaries address the public law dimensions of the term — the Roman annona system, military grain supply, or provincial frumentarii — which are significant for researchers working in Roman administrative or constitutional history. This is a consistent gap across the corpus.
Jurisdictional Note
Frumentum is a civil law term with no operative function in Anglo-American common law as a legal standard or rule. Its relevance in common law jurisdictions is purely historical and scholarly, arising in texts that engage with Roman law sources. In mixed jurisdiction systems with civil law foundations (Louisiana, Quebec, Scotland), frumentum may appear in historical commentary on property and obligations without functioning as binding positive law terminology.
