Meaning & origin
Issaiah is a modern respelling of the ancient name Isaiah, first recorded in U.S. data in 1990 and peaking in popularity in 2002. Since 2001, its usage has been in decline, and in 2025 it ranked 8,243, with an estimated 1 in 189,786 male newborns receiving the name. The variant's spelling with a double 's' reflects a broader trend of adapting traditional names with distinctive orthography, yet it has not achieved widespread adoption, having never broken into the top 1,000. Issaiah remains a rare choice, favored by parents seeking a familiar sound with a unique spelling.
Issaiah is a modern English variant of the biblical name Isaiah, which derives from the Hebrew Yeshayahu, meaning 'Yahweh is salvation'. The spelling with a double 's' is a recently coined alteration, likely influenced by names like Issac or the desire for a distinctive spelling. It has been in use in the United States since at least 1990, though it remains rare.
