The Story of Isaac
Isaac comes from the Hebrew 'Yitzhak', meaning 'he will laugh' or 'he laughs'. The name originates from the biblical story of Abraham and Sarah, whose son was named Isaac because Sarah laughed when God told her — at age 90 — that she would bear a son. This story of joy against impossible odds gives the name an undercurrent of miraculous delight.
Isaac climbed steadily into the US top 50 in the 2000s and 2010s, driven by a broader revival of biblical names with intellectual gravitas. Parents drawn to alternatives to the uber-popular Jacob found Isaac offered similar heritage with a more distinctive feel.
In the Abrahamic traditions of Judaism, Christianity, and Islam, Isaac (Ishaq) is the patriarch whose near-sacrifice on Mount Moriah is one of the most profound stories of faith. Sir Isaac Newton is the name's secular patron saint, making it associated with supreme intellectual achievement.
