Meaning & origin
Issac, a less common spelling of Isaac, has been in use in the United States since at least 1880. It reached its peak popularity in 2008, when it ranked 915th, though its usage has since declined. The name has remained relatively rare, with a current estimated rate of about 1 in 6,620 boys born in 2025. Historically, Issac has seen some regional popularity, particularly in Arkansas, Texas, and Arizona. While the traditional spelling Isaac is far more common, Issac offers a distinctive alternative to a classic biblical name with deep roots in Judeo-Christian and Islamic traditions.
Issac is a variant spelling of Isaac, which comes from the Hebrew name Yitzchaq, meaning 'he will laugh' or 'he laughs.' In the Old Testament, Isaac is the son of Abraham and Sarah, born in their old age, and his name reflects Sarah's laughter upon hearing she would bear a child. The name has been consistently used among Jewish, Christian, and Muslim communities for centuries. The spelling Issac, while less common, has been recorded in the United States since the late 19th century.
