non-bank

The word "non-bank" is a modern compound formed within English by combining the established negative prefix "non-" with the noun "bank." The prefix "non-" derives from Latin non, meaning "not," a strengthened form of the Proto-Indo-European negative particle ne-. The root "bank" entered English from Middle French banque or Italian banca, meaning "bench" or "counter," referring to the table used by money changers, with origins in a Germanic root. The compound "non-bank" logically and transparently denotes an entity that operates in the financial sphere ("bank") but is defined by its exclusion from the formal, licensed category ("non-").
