Meaning & Origin of Isaac

Isaac comes from the Hebrew name Yitzhak, derived from the word "tzachak" meaning "to laugh." In the Bible, God told Abraham and Sarah they would have a son in their old age, and Sarah laughed in disbelief — so the child was named Isaac, meaning "he will laugh" or "laughter." Isaac was one of the three patriarchs of the Israelites, and the story of the Binding of Isaac (the Akedah) is one of the most significant narratives in the Hebrew Bible. The name has been consistently used across Jewish and Christian communities for millennia and remains a strong, classic choice that balances biblical gravitas with warmth.
