What Does the Name Tadeo Mean?
Tadeo is the Spanish form of Thaddeus, a name that reached Spanish through Latin and Greek. The Greek form is Thaddaios (Θαδδαῖος), and it probably goes back to an Aramaic original. The Greek name appears in the New Testament for one of the twelve apostles, and its final origin is not certain. The most common explanation connects it to an Aramaic word sometimes transcribed as taday, meaning "heart" or "breast," which gives the customary meaning "heart." Some reference works instead link the name to Hebrew todah, "thanksgiving" or "praise." Because the apostle's name is preserved only in Greek, the exact Semitic original and its meaning remain uncertain.
Tadeo Name History & Origins
The Spanish form Tadeo corresponds to the Latin Thaddaeus of the Vulgate, where the apostle listed in Matthew 10:3 and Mark 3:18 is called Thaddaeus, a Latin rendering of Greek Thaddaios. Spanish translators used Tadeo for this apostle, and the form follows the ordinary Spanish shape of Latin names ending in -aeus, as Matthaeus became Mateo and Timotheus became Timoteo. In the Spanish New Testament, the apostle is called Tadeo, and he is traditionally identified with Judas, the son of James, and with the author of the Epistle of Jude. In Spanish-speaking countries he is widely known as San Judas Tadeo. The related Italian form is Taddeo, the Portuguese form is Tadeu, and the Polish form is Tadeusz; each developed from the same Latin source. Devotion to Saint Jude Thaddeus as a patron of desperate or lost causes is a later religious development and is separate from the origin of the name itself.
