Meaning & origin

Isayah is a modern respelling of the biblical name Isaiah, first recorded in the United States in 1992. Its popularity peaked in 2011, when it reached its highest rank of 2011, but has since fallen, with a trajectory showing a decline beginning around 2010. In 2025, it ranked 8910, with approximately 1 in 213,510 boys receiving the name. The variant spelling reflects a broader trend of phonetic and stylized updates to traditional names, though it remains much less common than the standard Isaiah. Isayah has no strong geographic concentration, appearing sparsely across the U.S. without any top state concentration.

Isayah is a modern English respelling of Isaiah, which derives from the Hebrew name Yeshayahu, meaning "Yahweh is salvation." Isaiah was a major prophet in the Old Testament, and the name has been common among English speakers since the Protestant Reformation. The spelling Isayah emerged in the late 20th century as part of a trend of creative orthography.
