Meaning & origin
Tadarius is a rare modern name that first appeared in U.S. records in 1986, a time when creative name combinations were gaining popularity. It reached its peak usage in 2001, though even then it remained uncommon. As of 2025, the name ranks 9,714th nationally, with an estimated 1 in 244,011 newborn boys receiving it. The name's trajectory has been stable, suggesting a small but consistent niche following. Its construction from the nickname Tad (itself derived from the Aramaic Thaddeus) and the fashionable suffix -arius places it alongside other modern coinages like Darius and Terrance. While it does not have strong ties to any particular state or region, Tadarius reflects the broader trend of invented names in African American and Southern naming traditions.
