Featured in baby name books
Thaddeus is an Aramaic name meaning “brave” or “having heart,” with variants such as Taddeo, Tadeo, and Thad. Thaddeus was one of Christ’s apostles, sometimes called Jude Thaddeus; it is uncommon without being odd, and the nicknames Tad and Taddy feel preppy. Thaddeus is also traced to Arabic with the meaning “beloved, adored,” while another book gives the Greek “stouthearted.” Notable bearers include abolitionist politician Thaddeus Stevens and Polish patriot Thaddeus Kosciuszko. Thaddeus Bach is the real name of Space Ghost, the cartoon crime fighter who patrols the galaxy with power bands and a monkey named Blip.
