Thiago: Baby Name Meaning, Nicknames and Numerology

What does the baby name “Thiago” mean?

Thiago is a Portuguese form of James by way of Santiago, ultimately rooted in the Hebrew name Jacob, traditionally interpreted as meaning "supplanter" or "one who follows closely at the heel."

Origin of the baby name Thiago

Thiago is a Portuguese given name that developed from the contraction of Santiago, itself a fusion of the Spanish Santo (saint) and Iago, the Iberian form of James. James traces back through Latin Jacobus to the Hebrew Ya'akov, traditionally interpreted as meaning "one who grasps the heel" or "supplanter," a reference to the biblical Jacob who was born grasping his twin brother's heel. Thiago is essentially the informal Portuguese version of this ancient name line, just as Diego is its Spanish equivalent.
