Definition
FELONIE is the Law French form of felony — the historical term used in medieval English and Norman legal writing to denote the class of serious criminal offenses distinguished from lesser wrongs (misdemeanors) and from treason, which stood above both. In the feudal framework from which the word emerged, felonie carried a specific technical meaning: an act so grave that it forfeited the offender's land, goods, and legal standing to the crown or overlord. The term appears throughout early legal manuscripts, Year Books, and treatises written in the Law French that dominated English legal practice from the Norman Conquest through roughly the seventeenth century.
As a dictionary entry, FELONIE is the historical spelling and Law French rendering of what modern legal systems call felony. It is not a distinct legal concept from felony — it is its ancestor form, encountered when reading medieval and early modern English sources in their original language.

Common Confusion
Researchers encountering FELONIE in a primary source may momentarily treat it as a different term from felony, or may mistake Law French spelling variation for a technical distinction. No such distinction exists. FELONIE, felonie, and felony refer to the same underlying concept; the orthographic differences reflect period and scribe, not meaning. Similarly, in feudal sources, felonie sometimes shades into the notion of a breach of feudal faith rather than a criminal act in the modern sense — a usage that has no equivalent in contemporary law. Context determines which sense is operative.

Why It Matters in Research
The primary research value of understanding FELONIE is navigational: when working in Burrill, Britton, Glanvill, Bracton, or the early Year Books, the researcher will encounter this spelling and must recognize it as felony without hesitation.
There is a more substantive trap worth noting. In early feudal sources — including Britton (the treatise Burrill's citation points to, written circa 1290) and the institutional writing on feudal law such as Guyot's Institutes of Feudal Law — felonie retains a dual meaning that later usage collapsed into one. It could mean (1) a serious crime triggering royal forfeiture of the offender's property, or (2) a breach of the feudal bond itself — the disloyalty of a vassal to a lord — regardless of whether a recognizable criminal act had occurred. These two meanings were related but not identical, and conflating them produces misreading of feudal land law sources. When Britton discusses felonie in chapters dealing with land tenure and forfeiture, the feudal-faith dimension is often primary. When later common law sources use the term, the criminal-classification dimension dominates.
Researchers working on topics such as felony disenfranchisement, felony murder, or the historical development of criminal grading should trace the concept through its modern entries rather than its historical spelling, but should not be confused when the historical form appears in sources along the way.

Historical Dictionary Support
Burrill's entry is spare: "L. Fr. Felony." with citations to Britton chapters 1, 4, 5, 6, 20, and 22, and to Guyot's Institutes of Feudal Law, chapter 12. This reflects Burrill's standard treatment of Law French forms — he identifies the term, gives the English equivalent, and points the reader to foundational sources. No substantive definition is offered because Burrill treats FELONIE as a form-word entry, expecting the researcher to consult FELONY for the full treatment.
The Guyot citation is significant context. Guyot's work addresses continental feudal law alongside the English tradition, reinforcing that the term's roots are pan-Norman rather than purely English — a useful reminder that early felony doctrine drew on a shared feudal legal culture across the Channel. Neither Burrill nor the sources he cites examine the shift in meaning from feudal disloyalty to criminal classification, which happened gradually across the twelfth through fourteenth centuries. That evolution is largely invisible in the historical dictionaries and must be reconstructed from the primary sources themselves.
