Meaning & origin

Kadarius is a modern American coinage that first appeared in official records in 1989. It reached peak popularity in 1995, when it ranked highest in usage. Since then, its trajectory has been steadily falling. In 2025, the name ranked 6,143, with roughly 1 in every 122,005 newborn boys receiving the name. The name was most popular during the 1990s, reflecting the era's trend toward inventive, sound-driven names with the popular Ka- prefix. Kadarius did not appear in any single top state concentration; its usage was spread thinly across the country. As a modern invention, it carries no traditional etymological meaning, but its structure echoes names like Darius and resonates with contemporary naming fashion.

Kadarius first appeared in the United States in 1989. It is a modern invented name, formed by combining the initial element Ka- (a fashionable prefix also seen in names like Kaden and Kaleb) with the suffix -darius, likely influenced by the Persian name Darius or similar names like Kedarius. The name has no traditional linguistic root or historical meaning beyond its contemporary construction.
