Meaning & Origin
A male given name from Ancient Greek, of common usage, variant of Thaddaeus.
Thaddeus is a boy's and girl's baby name of Aramaic origin, from the Aramaic Taddai, possibly meaning "heart" or "courageous heart," or alternatively from the Hebrew meaning "praised." Thaddeus was one of the twelve apostles of Jesus, also known as Jude.
Thaddeus is having a notable comeback as parents seek long, stately New Testament names with natural nickname options — Thad being the most obvious. With over 25,000 U.S. births recorded, it carries the weight of apostolic tradition with a grandly formal character.
