Tiago
Meaning
born of a re-division of Santiago, 'Saint James'
The story
Tiago exists because Portuguese re-cut a seam. Santiago, from the Latin Sancti Iacobi, Saint James, was reanalyzed as São Tiago rather than Santo Iago, and the piece after São stepped out as a name of its own, in print by 1681 in the Almeida Bible. The James behind it is the apostle whose tomb tradition places at Santiago de Compostela, destination of the Camino, Europe's great pilgrimage road since the early Middle Ages, feast day July 25. Brazil then did something extraordinary with the offshoot: 7,744 Tiagos born in the 1970s became 138,281 in the 1980s, a nearly eighteenfold leap in one decade, on the way to 363,388 in the 2022 census and rank 76 nationwide. The American record joined late and gently, from 51 in the 1980s to 1,327 in the 2010s. A name born from reinterpretation and carried by walking.
