Jurisprudence
Etymology
From Latin jurisprudentia, joining iuris, "of law," with prudentia, "knowledge, skill, foresight" (from providere, "to foresee"). The literal sense is "knowledge of the law." Over time it split into two uses: the philosophical study of law’s nature, and the accumulated pattern of decisions a court has produced in an area.
noun · /joor-iss-PROO-dunts/
The theory and philosophy of law, or the overall body of a court’s decisions on a subject.
What it names
The big-picture questions beneath any specific case — what law is, where its authority comes from, and how a court’s rulings hang together as a coherent whole.
Example
Decades of free-speech jurisprudence shaped how the judge framed the question.
