Meaning
“Possibly heart, from Thaddeus”
Tadeo is the Spanish form of Thaddeus, the name of one of the twelve apostles in the New Testament. The origin of Thaddeus is disputed: it may come from the Aramaic word for 'heart' or 'breast', or it may be an Aramaic adaptation of a Greek name such as Theodore.
