The term "Jurisprudence" is Latin origin- juris + prudentia. Juris connotes "law" and prudentia denotes "prudence/skill". Jurisprudence is thus the philosophical interpretation of the nature or purpose of Law.
It is the theory, philosophy or beliefs stated by various philosophers all over the world in various eras specifically posing the query- what the purpose of the law should be.
So the very purpose of jurisprudence, by means of its broad and manifold nature, mold for new challenges and it paves new avenues in the field of research with vast potentialities.
All these theories aim at - "What law is" or "What law aims at." that gives the rationality on principles behind laws as exist today
