Definition
A traverse jury is a petit jury — the body of jurors impaneled to hear and decide the facts in a trial, whether civil or criminal. The term is archaic and appears primarily in older legal texts, statutes, and court records. It is functionally synonymous with "trial jury" and is distinguished from a grand jury, which investigates and decides whether charges should be brought rather than deciding guilt or liability at trial.
The traverse jury's essential role is to evaluate evidence, find facts, and return a verdict. In criminal proceedings, that verdict determines guilt or innocence. In civil proceedings, it determines liability and, where applicable, damages.

Common Language
Modern common usage (Wiktionary): Defined simply as "petit jury" — the term is treated as a direct synonym with no elaboration.
Historical common usage (Webster's 1913): Webster's 1913 does not carry a standalone entry for "traverse jury," reflecting the term's status as legal vocabulary rather than general English.
The word "traverse" in ordinary English means to cross, pass over, or deny. In legal usage, "traverse" carries a specific procedural meaning — to deny or contradict a pleading — that is entirely separate from its use in "traverse jury." Researchers encountering "traverse" in historical legal documents should not assume the jury-related meaning; context is required to distinguish procedural traverses from jury references.

Common Confusion
TRAVERSE JURY vs. GRAND JURY: The most important distinction in the historical record. Both bodies are called "juries," but they perform entirely different functions. A grand jury determines whether sufficient evidence exists to charge a person; a traverse jury determines whether guilt or liability is established at trial. Older texts sometimes use "traverse jury" precisely to mark this contrast with the grand jury, which can cause confusion if a reader assumes the modifier "traverse" refers to something the jury does procedurally.
TRAVERSE JURY vs. TRAVERSE (procedural): An unrelated use of the same root word. A "traverse" in pleading practice is a formal denial of an allegation in the opposing party's pleading. The two uses of "traverse" share no functional connection. Researchers working in older equity or common law pleading records should treat these as entirely separate terms.

Why It Matters in Research
"Traverse jury" is a period marker. Its presence in a document is a reliable signal that the source predates the consolidation of modern procedural terminology. Researchers working with colonial-era records, early American statutes, English common law materials, or nineteenth-century case reporters will encounter it regularly. By the mid-twentieth century the term had largely disappeared from active legal usage in favor of "petit jury" or simply "jury."
The term's value in corpus research is primarily taxonomic: it helps researchers locate and cluster older procedural and jury-related materials. Because Bouvier's simply redirects to JURY without independent discussion, and Black's treats the term briefly as a cross-reference anchor, neither dictionary provides substantive analysis of the traverse jury's procedural rules. Researchers seeking doctrine — jury selection, unanimous verdict requirements, jury nullification, hung jury standards — must look beyond these dictionary entries entirely.
When traversing (in the modern research sense) from "traverse jury" to related doctrine, be alert to the fact that historical jury rules varied significantly between civil and criminal proceedings and between English and American practice. A source discussing traverse jury composition or verdict requirements in an English context may not map cleanly onto colonial American or early federal practice.

Historical Dictionary Support
Black's Law Dictionary provides the core identification: traverse jury equals petit jury equals trial jury, distinguished from the grand jury. The entry is spare and functional, serving primarily as a redirect.
Bouvier's Law Dictionary offers no independent entry, directing the reader to JURY. This omission is itself informative — Bouvier treats the term as transparent enough to require no separate analysis, which aligns with the term's role as a label rather than a term carrying independent doctrinal weight.
Neither source addresses the historical reasons for the "traverse" designation. The term derives from the older procedural vocabulary of English common law, where the trial jury was understood as the body that "traversed" — in the sense of crossing over or passing upon — the facts put in issue. This etymological thread is useful context for understanding why the term appears in some sources paired with pleading-related traverse language, but it does not affect the legal meaning of the term itself.

Jurisdictional Note
The term "traverse jury" appears across English common law jurisdictions but is most frequently encountered in American sources from the colonial period through the nineteenth century. It is not a term of art that carries distinct meaning in any particular U.S. state; its variation across jurisdictions is temporal rather than geographic.
