Meaning & origin

Issaac is a rare modern spelling of Isaac, first recorded in the United States in 1978. It reached its peak in 1983, but has never ranked in the top 1,000 names, with an estimated one in several million babies receiving the name each year. The trajectory of Issaac has been stable since its debut, with no recorded births in many years. Unlike the classic Isaac, which has enjoyed enduring popularity, Issaac remains a fringe variant, likely chosen by parents seeking a distinctive twist on a traditional name.

Issaac is a modern variant spelling of Isaac, which derives from the Hebrew name Yitzchak (יִצְחָק) meaning 'he will laugh.' The spelling with double 's' is a phonetic adaptation recorded in the United States since the late 20th century, though it remains rare. The name Isaac has deep roots in Judeo-Christian tradition as the son of Abraham and Sarah in the Book of Genesis.
