Thiago

A Brazilian spelling of Tiago, related to James and Jacob; traditionally associated with “holder of the heel” or “supplanter”.

Thiago is a masculine name in Brazilian Portuguese and a spelling variant of Tiago. Behind the compact form lies Santiago, “Saint James”, and, further back, the name family of Jacob. That history explains why different meaning lists offer “Saint James”, “supplanter” or “holder of the heel”: they describe different stages or traditional interpretations, rather than three separate origins. A Brazilian pronunciation is /t͡ʃi.ˈa.ɡu/, roughly chee-AH-goo, with the middle syllable stressed. The h is silent; it does not produce the English th sound. Thiago and Tiago therefore need not sound different simply because their spellings differ. To our ear, the clear central a and rounded ending give Thiago a lyrical, contemporary feel. The spelling with h looks a little more elaborate than Tiago, while retaining the same light rhythm.

Etymology: Thiago is a variant of Portuguese Tiago, which developed from Santiago. The older name belongs to the family of James and Jacob, ultimately from Hebrew Yaʿaqov. The familiar heel and supplanting explanations come from the biblical Jacob narrative; the original etymology is uncertain.
