Meaning & origin

Izack first appeared in U.S. birth records in 1995, a modern respelling of the enduring classic Isaac. The name reached its peak rank of 9,714 in 2006, with about 1 in 127,437 births that year. After some fluctuation, it has been rising in usage since 2022. As a creative variation, Izack offers parents a way to honor tradition while giving their child a distinctive name. Its spelling is straightforward and its nickname potential (Izzy, Zack) adds to its appeal. Though still rare, Izack aligns with the broader trend of names ending in the 'ack' sound.

Izack is a modern spelling variant of Isaac, which derives from the Hebrew name Yitzchaq (יִצְחָק), meaning 'he will laugh' or 'laughter.' The biblical Isaac was the son of Abraham and Sarah, and his name is associated with the laughter of his parents upon hearing God's promise of a son. The spelling Izack likely emerged in the late 20th century, gaining modest use in the United States as parents sought distinctive variations of classic names.
