Modern American creation, likely combining Thaddeus and Darius.
Tadarius is a contemporary American name, likely formed as a blend of the biblical Thaddeus and the Persian Darius. It follows a late 20th-century trend of creating rhythmic, multi-syllabic names within African American communities. While it lacks a singular ancient root, it carries the combined weight of its components' meanings: 'heart' and 'possessing goodness'.
