Thaddis

Thaddis is a masculine name that appears to be a variant of Thaddeus, which has ancient origins. The traditional Thaddeus derives from the Aramaic 'Taddai' or Greek 'Thaddaios,' possibly meaning 'gift of God' or 'courageous heart.' Thaddis represents a less common spelling variation that maintains the historical connections while offering a slightly different sound. The name has biblical associations through Thaddeus, one of Jesus's twelve apostles (though sometimes identified as Jude). While much rarer than Thaddeus, the Thaddis variant has seen occasional usage, particularly in southern United States communities. The name carries a scholarly, classical feel with its ancient roots, yet its uncommon spelling gives it a distinctive quality for those seeking something traditional but not commonplace.

Pronounced THAD-is.
