Izaiah is Hebrew in Origin.

Izaiah is a modern respelling of Isaiah, the English form of the Hebrew Yeshayahu/Yəsha‘yāhū, composed of yasha‘ “to save” and Yah(u) “the Lord,” yielding the meaning “Yahweh is salvation.” Through the Greek Septuagint Esaias and Latin Isaias, the name entered English, attached to the 8th-century BCE biblical prophet whose oracles shaped Jewish and Christian tradition. The “z” in Izaiah highlights the voiced consonant already present in English pronunciation.

As a given name, Isaiah thrived among English Puritans and reemerged broadly in the late 20th century; Izaiah rose in the United States from the 1990s as a contemporary, phonetic twist. Pronounced identically to Isaiah (eye-ZY-uh), it keeps the same religious resonance while feeling distinctive. International variants include Isaiah, Isiah, Isaias/Isaías, Isaia, Esaias, and Hebrew Yeshayahu. Common diminutives are Izzy and Zay.
