Definition
An Old Law French verb meaning "to swear." The term appears in medieval Anglo-Norman legal texts as a conjugated form of jurer, carrying the same root meaning: to take an oath or cause another to take an oath. In practice, the word surfaces in procedural contexts where a party was required to cause a specified number of persons—typically twelve—to be sworn, as in jury empanelment or compurgation proceedings.
The term is not a standalone legal concept but a functional word embedded in archaic procedural formulas. Its significance lies in its appearance within historical pleading and procedural texts rather than as a doctrine or cause of action.

Why It Matters in Research
Researchers encounter jorer almost exclusively in transcribed or quoted passages from medieval Anglo-Norman legal sources, particularly Britton (the late-thirteenth-century English legal treatise written in Law French). The term will not appear in modern indices, digests, or case reporters. A researcher who encounters it without familiarity with Law French may misread it as a proper noun, a place name, or an unrelated term.
The critical navigational point: jorer is a verb form, not a noun or a doctrine. When you see it in a primary source, the interpretive task is to identify who is being commanded to swear, how many persons are involved, and in what procedural posture. The phrase tost face jorer douze—"he shall presently cause twelve to swear"—points directly toward jury or compurgation procedure, and the surrounding text will usually clarify the context.
Corpus researchers working in Law French materials should treat jorer as a signal to cross-reference entries for jurer, jury, compurgation, and oath-taking procedure. Because Burrill catalogs it separately from jurer, historical sources may index the two terms independently, so searching only one may cause you to miss relevant passages.
The adjacent entry in Burrill—jornale/jurnale, denoting a day's plowing—is an entirely unrelated term that happens to follow jorer in alphabetical sequence. Do not conflate them; they share only proximity on the dictionary page.

Historical Dictionary Support
Burrill's Law Dictionary is the principal English-language historical source that records jorer as a discrete entry, identifying it as a Law French form of jurer and grounding it in Britton, chapter 30. Burrill's treatment is brief but accurate: it flags the term as a variant spelling, provides a phrase-level example, and cross-references the canonical form jurer. No other major English legal dictionary in the Law Mind corpus—not Bouvier, not Black's early editions—appears to carry a separate entry for jorer, suggesting that later lexicographers folded any relevant content under jurer and treated jorer as too minor a variant to merit independent treatment.
This creates a research gap: if you are working from a post-Burrill dictionary and searching for jorer by name, you will find nothing. You must enter through jurer or through the primary source directly.
Burrill's adjacent entry for jornale (a day's measure of land) is worth noting only to flag that the two terms are wholly unrelated; the physical proximity in the dictionary reflects alphabetical sequencing, not conceptual connection.
