Definition
To discommon is to deprive commonable lands of their commonable quality — that is, to convert land subject to rights of common into land from which those rights are extinguished or suspended, typically through enclosure, appropriation, or improvement by the owner. The act strips the land of its legal character as commonable, ending the rights of commoners to pasture, glean, or otherwise use the land in common.
The term operates as a verb describing an act done to land, not to persons. The result is that rights previously enjoyed by third parties over the land — rights of common — are terminated or rendered unenforceable as against the enclosed or appropriated portion.

Common Language
Modern common usage (Wiktionary): To deprive of the privilege of citizenship of a town or city; to deprive lands of commonable quality by enclosing or appropriating; to exclude from using a commonable resource; to deprive of the right to deal with undergraduates.
Historical common usage (Webster's 1913): To deprive of the right of common; to deprive of privileges; to deprive of commonable quality, as lands, by inclosing or appropriating.
The common and legal meanings share a core, but the legal meaning is narrower. Wiktionary's broader senses — deprivation of citizenship privileges, or the Oxford University usage concerning undergraduates — have no legal purchase. The legal term operates exclusively in the domain of land law and rights of common. Researchers encountering the term in historical general sources should resist importing those broader senses into legal contexts.

Why It Matters in Research
Discommon is a term of historical English land law, essentially extinct in modern American legal usage but alive in British legal history and in the history of agrarian law generally. Researchers working in the Law Mind corpus will encounter it almost exclusively in materials predating the twentieth century — treatises on common fields, enclosure history, and English real property law.
The critical research trap is anachronism: the concept of commonable land itself is largely obsolete in most jurisdictions. A researcher must first understand what commonable quality means — that land was legally open to exercise of rights of common by qualified commoners — before discommon becomes intelligible. Without that foundation, the definition reads as circular.
The enclosure movement is the primary historical context. Discommoning was one mechanism by which lords or owners terminated common rights, either through physical enclosure or through acts of appropriation that legally severed the commonable character of the land. The legal validity of discommoning without consent of commoners was contested, and the history of enclosure legislation bears directly on when and how the act could be accomplished lawfully.
For corpus researchers: sources referencing discommon will frequently sit adjacent to entries on right of common, approvement, enclosure, and waste. Burrill's cross-reference to Appropriare is a reliable navigational signal — follow it. The term does not appear in American legal dictionaries with any frequency, which means its appearance in an American source is itself a flag that the writer is drawing on English authority.

Historical Dictionary Support
The three source dictionaries — Black's (1st Ed.), Burrill's, and Black's (2nd Ed.) — are in verbatim or near-verbatim agreement: all three define discommon as depriving commonable lands of their commonable quality through enclosure, appropriation, or improvement. This uniformity across sources spanning Burrill's mid-nineteenth-century work through Black's revisions reflects the term's stable, narrow technical meaning rather than any active doctrinal development.
Burrill adds the cross-references to Common and Appropriare, which Black's omits. Those cross-references are substantively useful — Appropriare, the lord's act of taking in part of the waste or common for improvement, was the principal legal mechanism through which discommoning occurred. Black's compression loses that navigational value.
Webster's 1913 is unusually rich here and actually adds legal content: the definition distinguishes the act applied to persons (depriving of the right of common) from the act applied to land (depriving land of commonable quality). The legal dictionaries treat only the latter, but the former is historically attested and may appear in older English sources. Wiktionary's addition of the Oxford University sense — depriving someone of the right to deal with undergraduates — is genuine but entirely outside legal usage.
None of the historical dictionaries situate discommon within enclosure history or explain the contested legality of the act. For that context, researchers must move to treatises on English real property and agrarian history rather than dictionary sources.

Jurisdictional Note
Discommon is a term of English common law and has no meaningful independent development in American law, where the system of common fields and rights of common never took hold in the same form. Its appearance in American legal materials is derivative of English authority. Researchers working in jurisdictions with civil law traditions will find no counterpart.
