Definition
French. Literally, "without number." A term of art in the law of common, describing a right of common that is not limited to a fixed or certain number of animals. A right of common sans nombre does not entitle the commoner to put an unlimited or infinite number of beasts on the common; rather, it means the right is indefinite in number — not specified or certain by grant or prescription — as distinguished from a right of common limited to a stated head of livestock. The practical effect was that the number of animals was bounded by what the common could reasonably sustain, not by an express numerical ceiling in the grant.
Common Language
Modern common usage (Wiktionary): In heraldry, "sans nombre" describes a charge or division repeated many times across a field with no fixed count — covering the field without a set number of the repeating element.
Historical common usage (Webster's 1913): No entry recorded; the phrase was not naturalized into general English usage.
Editorial note: The heraldic and legal uses share a surface meaning of "uncounted" or "not fixed in number," but they operate in entirely different doctrinal contexts. The heraldic sense is purely descriptive of visual pattern. The legal sense carries substantive consequence: it determined the scope of a property right and the limits of a commoner's entitlement against other users of the common. Researchers encountering "sans nombre" in historical sources must determine from context whether the document is a legal instrument concerning rights of common or a record of armorial description.
Common Confusion
"Sans nombre" is sometimes misread as authorizing an unlimited right — that is, a right to put as many animals on the common as the commoner wishes. This misreading is directly addressed in the historical authorities. As Black's notes, the phrase "does not mean that the beasts are to be innumerable, but only indefinite; not certain." The distinction matters: an unlimited right of common would be incompatible with shared use, while an indefinite right still carried an implied obligation not to surcharge the common. The right was always subject to the doctrine against surcharging, even absent a fixed number.
Why It Matters in Research
This term appears almost exclusively in English common law sources concerning rights of common, and it surfaces primarily in pre-nineteenth-century materials — enclosure proceedings, manorial records, and treatises on real property and copyhold. Researchers working in early American property law may encounter it in colonial-era grants or in treatises that imported English common law doctrine wholesale, but it had little independent development in American courts and is largely obsolete in modern practice.
The key research trap is the phrase's superficial simplicity. "Without number" sounds like it confers an absolute or unlimited right, and some historical documents were drafted by parties who intended exactly that reading. Courts and commentators consistently rejected the unlimited interpretation, so a researcher finding "common sans nombre" in a grant document should understand that surrounding doctrine — particularly surcharging rules — constrained the right regardless of the grant's language.
Connections to the broader corpus: the term is inseparable from the parent concept of common of pasture, and researchers will need to understand the taxonomy of common rights (common appendant, common appurtenant, common in gross) to place sans nombre grants in proper context. Enclosure statutes progressively eliminated or commuted these rights in England, so the term's relevance diminishes sharply in sources after the major enclosure acts of the late eighteenth and early nineteenth centuries.
Historical Dictionary Support
The four source dictionaries agree on all substantive points. Black's (both editions), Rapalje & Lawrence, and Burrill all confirm that the phrase means "without number" in the sense of indefinite rather than unlimited. The Rapalje & Lawrence entry adds the most historical precision, tracing the interpretation to Babington C.J. in 11 Hen. VI. 22 B, as cited in Cooke on Inclosures — a useful pointer for researchers needing primary authority. Burrill's entry is the most compressed, cross-referencing the reader to "Common sans nombre" as the operative article rather than treating the French phrase as an independent head.
None of the historical dictionaries address the heraldic use, which is a meaningful gap for researchers working across legal and non-legal historical documents. None discuss American applications or reception of the doctrine, reflecting the term's essential status as English common law vocabulary with limited transatlantic migration.
Jurisdictional Note
The doctrine is English in origin and remained most fully developed in English common law. American courts had limited occasion to apply it because the specific form of manorial common rights that generated this terminology did not transplant fully into the colonial and early American property system. Researchers in English legal history and comparative property law will find the term most operative; American property researchers are unlikely to encounter it outside historical treatises.
