What does the name Izaiah mean?
Izaiah is a spelling of Isaiah, pronounced the same way, so it shares Isaiah's meaning and origin.
Isaiah comes from the Hebrew name Yeshayahu, borne by the 8th-century BC prophet whose book carries his name. It combines a root meaning 'salvation' or 'to save' with a short form of the divine name, so DMNES glosses it 'Yahweh is salvation'. English took the name through Greek Esaias and Latin Isaias; the Wycliffite Bible of 1395 spelled it Isaie or Ysaie. DMNES records it in England from the 1570s, when Protestant naming made Old Testament names more common.
יְשַׁעְיָהוּ (Biblical Hebrew, “Yeshayahu”)ישע (Hebrew, “save, salvation”)
