The 'San' prefix is the Spanish and Italian form of 'Saint', used to name settlements in honour of a Christian saint. The practice of naming towns after saints was central to the Catholic missionary expansion across the Americas, with Spanish and Portuguese missionaries naming new settlements after the saint whose feast day coincided with their arrival or the founding of a mission.

Understanding why places are named as they are gives us a window into history — the languages spoken, the people honoured, the landscapes encountered and the cultures that shaped the world we live in today. The field of toponymy (the study of place names) reveals that almost every name has a meaning, even when that meaning has been obscured by centuries of linguistic change.
