Definition
An archaic Law French term meaning a way, road, or highway. In medieval English legal usage, chymin (also spelled chimin, chemin, or chemyn) denoted a public road or right of passage — the physical route along which persons might lawfully travel. The term appears in early plea rolls and Year Books as part of the vocabulary of common law actions concerning obstruction of roads, rights of way, and related highway matters.
Why It Matters in Research
Researchers encountering chymin in historical legal sources should treat it as a spelling variant within a cluster of closely related forms. Law French orthography was inconsistent across centuries and scribal traditions, and the same underlying word appears in sources as chimin, chemin, chemyn, chymyn, and chymin interchangeably. A search limited to any single spelling will miss records using the others.
The term is most likely to surface in Year Book materials, early plea roll transcripts, and treatises drawing on those sources — particularly in actions concerning nuisance to highways, encroachments on public ways, or disputes over rights of passage. When a source entry directs "See Chimin," as Rapalje & Lawrence does here, the substantive legal content is carried under the cross-referenced headword, not the variant form. Researchers should follow that redirect and treat chymin as an access point, not an independent doctrine.
The highway law context of chymin connects forward to later English common law doctrine on public ways, which was eventually systematized under terms like highway, via regia, and public road. By the time English legal vocabulary stabilized in the early modern period, Law French road terminology had largely given way to English equivalents, and chymin had dropped from active legal use. Its appearance in a source is therefore a strong signal that the document or authority being cited dates from the medieval period or is itself citing medieval authority.
Historical Dictionary Support
Burrill provides the core substance: chymin is Law French for "a way or road; a highway," with a citation to the Year Books of Edward III's reign (Year Book P. 6 Edw. III. 48). This single source gives researchers both the meaning and a period anchor — the term was in active legal use in the first half of the fourteenth century.
Rapalje and Lawrence offer no independent definition, directing the reader instead to the headword Chimin. This cross-referential treatment confirms that by the time of that dictionary's compilation, chymin was understood as a variant spelling rather than a distinct term warranting its own analysis.
Neither source elaborates on the legal consequences that attached to obstruction or misuse of a chymin, nor do they describe how highway disputes were pleaded. For that doctrinal content, researchers must move from the dictionary entry to the Year Book materials cited and to secondary treatments of medieval highway law.
