Meaning and origin of Izaiah
Izaiah is a Hebrew and American (modern coinage) name that means “Yahweh is salvation”.
Izaiah is a modern spelling of Isaiah, from the Hebrew Yeshayahu, "Yahweh is salvation". Isaiah is one of the major prophets of the Hebrew Bible, active in Jerusalem in the eighth century BC, and the book that bears his name is among the most quoted in Jewish and Christian tradition. The spelling with a Z reflects the way the name is pronounced and gives it a contemporary look. It is used mostly in the United States. The name sounds strong yet gentle, and Zay and Izzy are possible nicknames. Isaiah remains the standard spelling for those who prefer it.
