Etymology

Origin of juror

1250–1300; Middle English jurour < Anglo-French (compare Old French jureur ), equivalent to Old French jur ( er ) to swear (< Latin jūrāre ) + -our -or ²

Explanation

Anyone who's a member of a jury in a court of law is called a juror. When you serve as a juror, you're part of a group that hears evidence in a trial and gives a verdict. When someone gets called for jury duty, it's an opportunity to be a juror for a trial. A juror is typically one of twelve people who swear to make an impartial, unbiased decision based on legal evidence. The jurors must come to a unanimous agreement about their verdict after all evidence is presented, generally either "guilty" or "not guilty." The Latin root is iuratorem, or "swearer," from iurare, "to swear."
