Definition
A Latin maxim meaning "denomination should be made from the more worthy." The principle holds that when naming, classifying, or describing a thing composed of multiple elements or qualities, the designation should derive from its most significant, most dignified, or most legally consequential component. In feudal and property contexts, this meant that the name or legal characterization of a grant, estate, or right should reflect its highest or most substantial incident rather than a lesser one.
The full form of the maxim as it appears in legal sources is: *Denominatio fieri debet a dignioribus* — denomination ought to be made from the more worthy.

Common Confusion
This maxim is occasionally grouped loosely with *accessorium sequitur principale* and *noscitur a sociis* as if they are interchangeable rules of construction. They are related but distinct. *Accessorium sequitur principale* addresses what happens to incidental rights when the principal right is transferred or extinguished. *Denominatio fieri debet a dignioribus* addresses the anterior question of characterization — what the thing should be *called* and therefore what legal regime governs it. The denominatio maxim resolves classification; the accessory maxim resolves consequence.

Why It Matters in Research
This maxim operates as an interpretive rule rather than a standalone substantive doctrine, and researchers are most likely to encounter it in three contexts:
**Feudal property law.** Black's (2nd Ed.) places the maxim directly in the context of the fief and its incidents, citing Guyot's *Institutions Féodales*. In that setting, the maxim governed how a composite feudal grant should be named and what law applied to it — the character of the dominant right controlled the whole. Researchers working in feudal tenure, copyhold, or early English land law should be alert to this maxim as a rule of characterization that shaped which legal regime governed mixed or compound grants.
**Rules of construction and interpretation.** Beyond feudal law, the maxim was applied more broadly as a canon of legal construction: when a transaction or instrument combined elements of different legal character, courts could invoke this principle to classify the whole by its worthiest or most significant part. This intersects with similar maxims such as *accessorium sequitur principale* (the accessory follows the principal) and *noscitur a sociis* (a thing is known by its associates).
**Maxim citation in historical sources.** Because this is a pure Latin maxim with narrow feudal roots, it appears infrequently in modern case law. Researchers using 19th-century treatises, civil law commentaries, or continental sources on feudal institutions are more likely to encounter it than those working in modern common law materials. The Guyot citation in Black's points to the French institutional tradition, not English common law directly — a useful signal about which corpus is most relevant.
**Trap for researchers:** Do not conflate the maxim's role as an interpretive guide with any substantive rule about what makes one thing "more worthy" than another. The maxim tells you *how* to name; it does not independently determine *what* is more worthy in a given context. That judgment depended on the specific legal framework (feudal hierarchy, instrument type, nature of the rights) and must be resolved by reference to the surrounding doctrine.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) presents the maxim in compressed form, embedding it immediately after a definition of the fief and its incidents, and attributing it to Guyot's *Institutions Féodales*, chapter 3. This placement is instructive: Black's treats the maxim not as a freestanding principle of general application but as a rule belonging to the law of feudal tenures, specifically to the problem of how composite feudal rights should be denominated and understood.
The historical record for this maxim in English-language legal dictionaries is thin. It does not appear as a developed entry in Bouvier's, and Stroud's does not treat it independently. Its primary transmission into the common law tradition appears to have been through civilian and feudal commentators rather than through English equity or common law judges. Researchers should therefore give more weight to continental institutional sources than to English case digests when tracing this maxim's application.
What historical sources collectively do not address is any modern analogue or survival of the principle in contemporary property or contract law. The maxim is functionally dormant in active litigation but retains value as evidence of interpretive method in historical instruments.
