Definition
An archaic Latin and Law French term appearing in early English legal records. "Jor" (also rendered as Joefdy, Joendie, Joedy, and related spellings) is a contracted or corrupted form meaning "Thursday" — the day of the week — as it appeared in medieval legal pleadings, writs, court rolls, and similar instruments where the day of a legal act or appearance was recorded. The term belongs to the vocabulary of Law French, the procedural language of English courts from roughly the Norman Conquest through the early modern period.
In legal instruments of that era, precise dating by day of the week and liturgical calendar was standard practice. "Jor" and its variant spellings reflect the phonetic and scribal drift common in Law French legal manuscripts, where the same term might appear in several forms across different scribes, courts, and centuries.
Why It Matters in Research
Researchers working with medieval English court records, plea rolls, year books, or early conveyancing instruments will encounter this term and its variants as part of date clauses. Failure to recognize "Jor" or its cognate spellings as a temporal marker for Thursday can cause misreading of the procedural timeline in a case or the execution date of a document.
Scribal variation is the primary trap here. The spellings Joefdy, Joendie, Joedy, and Jor may appear within the same collection of records, or even within a single document, without any signal that they refer to the same word. Researchers should treat all such forms as potentially equivalent when reconstructing dates.
This term illustrates a broader research challenge in Law French sources: words were recorded phonetically and inconsistently, and no standardized orthography governed legal scribes. When dating of a legal act is material to your research — for questions of jurisdictional timing, default, appearance, or limitations — encountering one of these variant forms and not recognizing it as "Thursday" can silently corrupt your analysis.
Cross-corpus connections: Researchers encountering "Jor" in plea rolls or writs should also be familiar with the full Law French calendar vocabulary. Other days of the week appear in similar contracted forms throughout the same source material.
Historical Dictionary Support
Burrill's Law Dictionary is the sole shelf source providing any treatment of this term, and its entry is fragmentary — appearing as a parenthetical within a broader entry and listing the variant spellings without extended discussion. Burrill credits Kelham, referring to Robert Kelham's Dictionary of the Norman or Old French Language (1779), which remains one of the principal reference works for Law French vocabulary and is the deeper source for anyone needing to trace these spellings systematically.
No other major historical legal dictionaries in the standard shelf — including Jacob's Law Dictionary, Tomlin's Law Dictionary, or Black's earlier editions — provide a discrete entry for "Jor." This absence is itself informative: the term was recognized as sufficiently specialized or archaic that even comprehensive historical dictionaries treated it only incidentally. Researchers should not expect cross-coverage here and should go directly to Kelham or to diplomatic glossaries for medieval English records when the term is contested.
Jurisdictional Note
This term is specific to English legal sources and their derivatives in jurisdictions that inherited the English common law tradition and its Law French procedural vocabulary. It has no counterpart in civilian or continental legal systems.
