Thiago
Thiago Name Meaning, Origin & Popularity
tee-AH-goh
Meaning of Thiago: Thiago derives from the Portuguese Tiago, itself drawn from the medieval Iberian form of Santo Iago meaning Saint James. The ultimate Hebrew root is Ya'aqov< The h in Thiago emerged in Brazilian Portuguese spelling reforms during the 20th century.
Saint James the Greater, one of the twelve apostles, gave the name its Christian weight. Iberian pilgrimage to Santiago de Compostela in Galicia spread devotion across the Portuguese-speaking world, and the contracted form Tiago established itself across Brazil, Portugal, Angola, and Mozambique from the medieval era onward.
Brazilian orthography distinguishes Thiago from Tiago without changing pronunciation. Parents in Brazil, which accounts for the largest Portuguese-speaking population, have favored the h-spelling since the 1960s, viewing it as the more stylish register. Argentine and Spanish-speaking parents then borrowed the Brazilian form during the late 20th century.
