Basque form of Santiago, itself from Sant Iago (Saint James), a Hebrew name meaning 'supplanter.'
Xanti is a Basque pet form of Santiago, the Spanish name for Saint James the Apostle. Santiago itself is a compression of "Sant Iago" — Saint James — with Iago being the Iberian rendering of the Hebrew Yaakov (Jacob), meaning "supplanter" or, in more generous interpretations, "holder of the heel" or "may God protect."
The Camino de Santiago pilgrimage route — one of the great spiritual journeys of the medieval world — made Santiago one of the most culturally freighted names in the Iberian Peninsula, synonymous with faith, endurance, and destination. In the Basque Country, the name was adapted with the characteristic Basque 'X' prefix, yielding Xanti as the familiar, intimate form used among family and friends. The Basque language, likely the oldest surviving language in Western Europe with no known relatives, has its own phonetic rules: the initial 'X' is pronounced like the 'ch' in "loch" or the 'sh' in "shout," giving Xanti a warmth and distinctiveness quite different from its visual impression on paper.
As a given name exported beyond the Basque region, Xanti carries the weight of pilgrimage culture, Basque pride, and apostolic tradition while looking unmistakably contemporary. The rare opening letter signals parents who want something rooted, European, and phonetically surprising — a name that rewards the moment someone asks how to say it.
