History & Origin

The recorded meaning of Kassius in German is 'empty, vain' — not the warmest sense to attach to a child, and worth knowing before choosing it. The spelling with a K and the -ius ending give it a classical, Roman flavour, though the meaning on file here is the German one. With no listed variations or notable bearers in this data, there is little more that can be said honestly about its history.

The double effect of the hard K opening and the trailing -ius makes it feel both modern and antique at once.
