Meaning and origin of Isiah
Isiah is a Hebrew and American (modern coinage) name that means “God is salvation; variant of Isaiah”.
Isiah is a spelling of Isaiah, from the Hebrew Yeshayahu, meaning God is salvation. Isaiah is one of the major prophets of the Hebrew Bible, and the book bearing his name is among the most quoted in Jewish and Christian tradition. The spelling Isiah became familiar in the United States through the basketball star Isiah Thomas. It is pronounced the same as Isaiah and keeps the same meaning while offering a simpler written form. Izzy and Zay are possible nicknames.
