Jurisprudence, derived from the Latin 'jurisprudentia', refers to the knowledge and application of law and encompasses various legal concepts, theories, and classifications. It is studied from multiple perspectives, with key contributors like Jeremy Bentham, John Austin, and H.L.A. Hart providing differing definitions and classifications, such as general vs. particular jurisprudence and analytical vs. evaluative types. The study of jurisprudence serves as both a guide for legal practitioners and a means to understand the functioning of legal systems in society.
