A more thorough explanation:

Definition: Voir dire is a French term that means "to speak the truth." It is a process used in court to select jurors for a trial. During voir dire, potential jurors are questioned by either the judge or a lawyer to determine if they are suitable to serve on a jury. It is also used to question witnesses, especially experts, to determine their competence to testify.

Example: In a criminal trial, the judge may ask potential jurors if they have any biases or prejudices that would prevent them from being fair and impartial. The lawyers may also ask questions to determine if the potential jurors have any personal connections to the case or the parties involved.

Example: During a medical malpractice trial, the lawyers may question potential expert witnesses during voir dire to determine their qualifications and expertise in the field of medicine.

These examples illustrate how voir dire is used to select impartial jurors and competent witnesses for a trial. It is an important process in ensuring a fair and just legal system.
