Definition
A Latin term from Roman civil law meaning "to be borne" or "to be carried on or about the person." The term described the manner in which something — most commonly a weapon or an item of personal property — was physically carried or kept by an individual directly on their body. This was a technical distinction bearing legal consequence in Roman law, separating things worn or held on the person from things transported by other means.
Common Language
Modern common usage (Wiktionary): An Italian surname.
Historical common usage: Not applicable as an English common word; ferri is Latin and Italian in origin.
The gap here is total rather than partial. In ordinary English usage, ferri functions only as a proper name. Its legal significance is entirely confined to the Roman civil law tradition, where it operates as a technical term of art with no meaningful modern English counterpart.
Common Confusion
FERRI vs. PORTARI: These two Latin civil law terms are companion concepts and are understood only in relation to each other. Ferri denoted carrying on or about the person — in one's hands, at one's belt, under one's garments. Portari denoted carriage by an animal, such as in a saddlebag or pack. The distinction mattered in Roman law when statutes or edicts regulated the bearing of weapons or goods, because the prohibition or permission applicable to one mode of carriage did not necessarily apply to the other. Researchers encountering one term in a civil law source should expect the other nearby.
Why It Matters in Research
Ferri appears almost exclusively in sources engaging directly with the Digest of Justinian, specifically Digest 50.16.235, a title devoted to the meanings of legal words and expressions. Researchers will encounter it not as a standalone doctrine but as a term of construction — invoked when interpreting earlier Roman law texts that use the word ferre or its variants in the context of weapons, property, or personal effects.
In the Law Mind corpus, ferri is most likely to surface in treatises on Roman law, civil law commentaries, and historical works on the law of arms or the carrying of weapons. It is unlikely to appear as operative law in common law sources except in scholarly annotation or comparative discussion. When a common law writer cites the distinction between ferri and portari, they are typically drawing on civilian learning to illuminate a concept (such as what it means to "bear arms" or to "carry" a concealed weapon) rather than applying Roman law directly.
The practical research trap is assuming the term is merely ornamental Latin. In context, the ferri/portari distinction was a genuine interpretive tool in civil law jurisdictions and in early modern legal scholarship, and the distinction between personal carriage and animal-borne transport had downstream consequences for liability, forfeiture, and the scope of regulatory prohibitions.
Historical Dictionary Support
Black's, Burrill's, and Bouvier's are in complete agreement on this term — all three define it identically and all three anchor the definition to Digest 50.16.235. This unanimity reflects the term's narrow and settled scope: it never acquired competing definitions or jurisdictional variations. Burrill's adds the Latin "to be borne" phrasing most explicitly and is marginally the most precise in its wording. Bouvier's is the most compressed.
None of the historical dictionaries elaborate on the practical legal consequences of the distinction or provide examples of its application in adjudicated cases. This is a limitation worth noting: a researcher who finds the term defined in these dictionaries and proceeds no further will understand what the word means but will not understand why the distinction was drawn or how it was applied. For that, the Digest itself and civil law commentators are the necessary next step.
