Nunnius

Nunnius is a name of ancient Roman origin, derived from the Latin word 'nonus', meaning 'ninth'. It was likely given to a ninth-born child or a child born in the ninth month. While not widely used as a given name in modern times, its root is found in various Roman family names (nomina) and cognomina.

The name's usage was primarily within the Roman Empire and its sphere of influence. It is a rare example of a numerical name that saw some use, though it never achieved the widespread popularity of other Roman names. Its historical significance lies in its connection to Roman naming conventions and the Latin language.
