Meaning and origin
Thiago means Inherited meaning of 'supplanter' or 'holder of the heel,' carried through the Ya'akov/Jacob > Iacomus > Sant Iago > Santiago > Tiago/Thiago chain; functionally, the name's most immediate common association is 'Saint James' rather than the literal ancient Hebrew root.
Deeply embedded in Iberian and Latin American Catholic culture through its connection to Saint James (Santiago), one of the Twelve Apostles; in contemporary usage, particularly in Brazil, it functions as a very common, unremarkable modern boy's name rather than one felt as overtly religious.
Documented origin: Portuguese form of James, via Tiago, a contraction of Santiago, which is itself a fusion of the Late Latin 'Sanctus Iacobus' ('Saint James/Jacob'). It ultimately traces to the Hebrew name Ya'akov (Jacob).

Real-world considerations
- Popular — #50 in the latest U.S. ranking.
- Spelling note: Frequently confused with or misspelled as the closely related forms Tiago (the standard Portuguese/European spelling), Diego (the Spanish cognate), and Santiago (the full uncontracted form); minor misspellings like 'Tiagoe' or 'Teigo' also appear per pronunciation-aggregator sites..
- The etymological chain from Thiago back to Tiago/Santiago/Sant Iago is well documented and not seriously disputed. What is less precisely nailed down in accessible sources is the exact historical timeline and geography of when the 'Thiago' spelling (versus the older 'Tiago') became the dominant Brazilian form — sources agree Thiago is 'mostly used in Brazil' while Tiago dominates in Portugal, but do not give an exact date for when this spelling split occurred.
