Meaning & origin
Isaih is a rare spelling variant of the classic name Isaiah. First recorded in 1894, it never achieved widespread use, ranking 9714th for boys in 2025 with only 1 in 244,011 baby boys receiving the name that year. Its peak year was its first recorded year, 1894, which suggests it may have been a one-time coinage that occasionally resurfaces. The name has been on a falling trajectory since 1998, and it is not associated with any particular U.S. state or cultural trend. While Isaiah has biblical roots and longstanding popularity, Isaih remains an uncommon alternative that may appeal to parents seeking a distinctive spelling.
Isaih is a less common spelling variant of Isaiah, a name derived from the Hebrew Yeshayahu, meaning 'Yahweh is salvation.' Isaiah was a major prophet in the Old Testament, and the name has been used among Christians and Jews for centuries. The variant spelling Isaih appears to have emerged in the late 19th century in the United States, possibly as a simplified form, but never gained widespread usage.
