What does the baby name “Isaias” mean?
Isaias is the Portuguese form of Isaiah, a prophetic name from ancient Hebrew meaning "God is salvation." Rich with biblical history and warmth, it carries the legacy of one of the Hebrew Bible's most celebrated prophets.
Origin of the baby name Isaias
Isaias derives from the Hebrew name Yeshayahu, composed of "Yeshua," meaning salvation, and "Yah," a shortened form of the divine name YHWH. The name passed into Greek as Esaias and into Latin as Isaias, the form that became standard in the Vulgate Bible and spread through Catholic Europe. Portuguese preserved this Latin form, while English developed the variant Isaiah from the same Hebrew source. All forms share the same core meaning: God saves, or salvation comes from God.
