Nafka mina

From Wikipedia, the free encyclopedia

Nafka Mina (aramaic: נפקא מינה) is a Talmudic term which means practical difference. It is often used in the phrase Mai nafka mina?(מאי נפקא מינה), which means "What is the practical (or most important) difference?"

It literally means "goes out from it" - indicating that in a distinction between conceptual categories, there must be some practical effect that emerges from the distinct categories as conceived.
