    Mostly workable

About the name

Meaning

empty.

Origin and history

Cassius (Latin). Latin. Borne by Lucius Cassius Dio, a 3rd-century Roman historian, and by several early Christian saints. In American history, it is most prominently the birth name of boxer Muhammad Ali (1942-2016), who was named Cassius Marcellus Clay Jr. after his father, himself named for 19th-century American abolitionist and politician Cassius Marcellus Clay (1810-1903).

Style through life

Reads as a strong, classical-feeling adult name in US English, carrying the gravitas of a Roman family name and the specific historical resonance of Muhammad Ali's birth name. Three syllables with a somewhat unusual English spelling (the "-ius" ending is uncommon among common US given names), which can require some early spelling correction, though the anglicized pronunciation ("KASH-us") is not itself difficult once learned.

Regional and cultural use

Originated as a Roman family name (nomen gentilicium) rather than a personal given name in antiquity; its modern use as a first name draws heavily on its association with 20th-century American history via Muhammad Ali's birth name.

Bottom line

On its own, Cassius holds up well, with a single specific point worth checking before you decide. If it stays on the shortlist, show the written name to someone seeing it for the first time and note where their pronunciation lands.
