grand-jury

The term 'grand jury' is a compound noun formed from two distinct legal traditions. The word 'jury' originates from the Latin verb 'iurare,' meaning "to swear," reflecting the core duty of its members to take an oath. 'Grand,' from Latin 'grandis' (large, great), was appended in the legal context of Anglo-Norman law to distinguish this larger, investigative body from the smaller 'petit' (small) trial jury. The concept evolved in medieval England as a means for the crown to investigate crimes and present formal accusations, with the "grand" designation signifying its superior authority and broader scope compared to the trial jury that decides guilt. Thus, the term literally denotes the "principal sworn body" responsible for the indictment process.
