Isiah is Hebrew in Origin.

Isiah is an English variant spelling of Isaiah, ultimately from the Hebrew name Yeshayahu/Yesha‘yahu, formed from yasha‘ (“to save”) and the divine element Yah(u), yielding the meaning “Yahweh is salvation” or “the Lord is salvation.” Through Greek Esaias and Latin Isaias, the name spread across Europe, producing forms such as Isaia (Italian), Isaías (Spanish/Portuguese), Jesaja (German/Scandinavian), and Isaiah in English; modern respellings include Izaiah.

In English, Isaiah entered regular use after the Reformation and was favored by Puritans; the streamlined spelling Isiah gained independent currency in the United States, sometimes arising from records and later reinforced by cultural figures like NBA star Isiah Thomas. Usage remains periodic yet familiar, especially in African-American communities. Common short forms include Izzy, Zay, and occasionally Sai. Though spelled differently, Isiah typically carries the same biblical resonance and meaning as Isaiah.
