Principi

Principi is an Italian term that functions as both a common noun and a surname. In Italian, principi is the plural of principio (principle) and also the plural of principe (prince). As a noun, it appears in contexts such as principi etici (ethical principles) or principi di bilancio (budget principles); in historical writing it could refer to princes, depending on era and usage.

As a surname, Principi is of Italian origin. Surnames formed from titles and roles are common in Italy, and Principi may derive from a family associated with princely status, from a nickname for someone deemed princely, or from a toponymic source linked to land or a place connected to a prince. The surname is found mainly in Italy, with bearers who have migrated to other regions and to the broader Italian diaspora.

In contemporary usage, Principi appears in text as the plural noun for principles or as a family name. It is distinct from the singular forms principio (principle) and principe (prince), though all share a common Latin root, principium.
