Pronunciation

KASH-usListen

Cassius traces back to a Roman family name of Latin origin, pronounced KASH-us. You may see it explained online as meaning 'hollow' or 'vain' from the Latin cassus, but that link isn't actually substantiated — Wiktionary confirms only that Cassius was a Roman clan name, not what it meant. For a parent who wants a name with real Roman roots but no fixed English meaning attached, that's simply where it stands.
