How This Name Lives

AT SCHOOL & DAY TO DAY

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.

INTO ADULTHOOD

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.

Cultural Footprint

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.
