What Does the Name Tadej Mean?
Tadej is the Slovene form of Thaddeus, a name whose ultimate meaning is uncertain. It derives from Greek Thaddaios (Θαδδαῖος), a name of Aramaic origin that passed into Latin as Thaddeus. One common explanation connects it with Aramaic taddā, "breast" or "heart," and gives the customary sense "large-hearted" or "courageous." Another explanation derives it from Hebrew tōdāh, "praise" or "thanksgiving." The evidence does not clearly decide between them, so "heart" is best treated as a traditional interpretation rather than a settled literal translation.
Tadej Name History & Origins
The name appears in the New Testament as Thaddaios, the name or byname of one of the apostles, in the Gospels of Matthew and Mark. Later Christian tradition identifies this apostle with Jude, which is why the two names are linked as Jude Thaddeus. The Greek form passed into Latin as Thaddeus and was adopted in Christian Europe. In Slovene it became Tadej, a domestic adaptation of the Latin name. Related forms in neighboring languages include Polish Tadeusz, Czech Tadeáš, and Croatian Tadija.
In Slovene name-day calendars, Tadej is associated with October 28, the feast of Saints Simon and Jude. The name has been used as a traditional Slovene masculine given name.
