Definition
Voir dire (also spelled voire dire) is a preliminary examination conducted by a court to determine the competency, qualifications, or impartiality of a person before they are permitted to participate in a legal proceeding. The term is used in two principal contexts:
1. JURY VOIR DIRE: The examination of prospective jurors (venire members) by the judge, attorneys, or both, to identify bias, prejudice, or disqualifying connections to the case. This is the dominant modern usage. Through voir dire, parties may challenge jurors for cause (specific disqualifying reason) or exercise peremptory challenges (limited in number, requiring no stated reason, subject to constitutional constraints).
2. WITNESS VOIR DIRE: A preliminary examination of a witness — outside the presence of the jury — to assess competency to testify, the admissibility of specific evidence, or qualifications to offer expert opinion. This usage is older and appears frequently in historical sources.
The phrase derives from Old French and translates roughly as "to speak the truth" or "to say truly." The oath taken in this proceeding was the original mechanism of the examination: the person examined swore to answer truthfully before the court ruled on their eligibility.

Common Language
Modern common usage (Wiktionary): "Voir dire" is defined as a preliminary examination of a prospective juror or witness by a judge or lawyers; the process by which jurors are selected for trial.
Historical common usage (Webster's 1913): Webster's 1913 does not carry a separate entry for voir dire, treating it as legal vocabulary rather than general English.
The common modern understanding — particularly in popular and media usage — reduces voir dire almost entirely to jury selection. Legal usage retains the broader sense: voir dire applies equally to preliminary examination of witnesses, experts, and evidence. A researcher who encounters "voir dire" in an older case report may be reading about a competency challenge to a witness, not jury selection at all.

Common Confusion
VOIRE DIRE vs. CHALLENGE FOR CAUSE: Voir dire is the examination process; a challenge for cause is one possible outcome of that process. The two are frequently conflated. Voir dire can result in a challenge for cause, a peremptory challenge, or no challenge — the examination itself is neutral.
VOIRE DIRE vs. IN CAMERA EXAMINATION: Both proceedings can occur outside the jury's presence, but an in camera examination concerns confidential or privileged matters and involves no competency determination. Voir dire is specifically a truth-qualification inquiry.

Recognized Forms
/SUBTYPES
1. JURY VOIR DIRE: Examination of venire members before empanelment. May be conducted by the judge alone, by counsel, or jointly, depending on jurisdiction and court rules.
2. WITNESS/EXPERT VOIR DIRE: Examination of a proposed witness — most commonly an expert — to establish qualifications before testimony is admitted. Courts may conduct this outside the jury's hearing.
3. EVIDENCE VOIR DIRE: A preliminary hearing on the admissibility of specific evidence, particularly confessions or statements, where the court must determine foundational facts before ruling on admission.

Why It Matters in Research
The term has undergone a functional shift that will mislead researchers working across historical and modern sources. In older materials — through roughly the nineteenth century — voir dire most commonly refers to the witness competency examination. Burrill's entry makes this plain: the examination existed to flush out interested witnesses who might have been disqualified under the old interested-party rules. Modern researchers will recognize the term primarily from jury selection, but that usage did not displace the witness-examination sense until the twentieth century.
Researchers working in the Law Mind corpus should flag this shift carefully. A nineteenth-century case discussing voir dire almost certainly concerns a witness's disqualifying interest, not jury empanelment. The procedural stakes were different: under common law rules that barred interested parties from testifying, voir dire was a gatekeeping mechanism of real consequence. After interest ceased to be a ground for disqualification (by statute in most jurisdictions during the mid-to-late 1800s), the witness-voir-dire function diminished and jury voir dire expanded to fill the term's practical meaning.
The constitutional dimension of modern jury voir dire — particularly the Batson line of cases restricting race-based and sex-based peremptory challenges — does not appear in any historical dictionary source. Researchers examining jury selection fairness or equal protection arguments must move beyond the historical dictionaries entirely. The Law Mind Encyclopedia entry on jury selection covers this dimension directly.
For corpus connections: voir dire intersects with competency, challenge for cause, peremptory challenge, expert witness qualification, and the admissibility of confessions. Each of these threads carries its own historical development and should be traced separately.

Historical Dictionary Support
Burrill's entry frames voir dire entirely as a witness-competency examination — the oath administered to a suspected interested witness before the court determines whether to disqualify them. Burrill cites Cowell and references the older French expression à dire le verité as a parallel form. This confirms that the term's legal home, as of Burrill's writing, was the witness stand, not the jury box.
Burrill does not address jury voir dire, which reflects the state of the doctrine at the time of his writing. The modern jury-selection sense of the term is simply absent from the historical dictionary corpus available here. Researchers should treat Burrill's definition as accurate for its period and inapplicable as a complete definition for modern practice.
The spelling "voire dire" (with the terminal -e on voire) appears in Burrill and some other older sources; "voir dire" (without the terminal -e) is the standard modern form. The variation is orthographic, not substantive.

Jurisdictional Note
Jury voir dire procedure varies significantly across federal and state courts. Federal courts tend to limit attorney-conducted voir dire, with judges managing the examination more closely; many state courts permit broader attorney participation. The scope of permissible voir dire questions — and what constitutes adequate inquiry into bias — is jurisdiction-specific and has been the subject of appellate litigation.
