Isaac Origin and Meaning

The name Isaac is a boy's name of Hebrew, Aboriginal origin meaning "laughter".

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.

Isaac evolved from the name Yitzchaq, derived from the Hebrew word tzachaq, meaning "to laugh." In the Old Testament, Isaac was the long-awaited son of the elderly Sarah and 100-year-old Abraham, so old that their news provoked laughter, giving the name its meaning. Isaac is used as a given name among Jews, Christians, and Muslims alike.

A baby given this name can point to many distinguished namesakes, including Isaacs (and Izaaks) Newton, Walton, Bashevis Singer, Asimov, Stern, Hayes, and Hanson.

Isaac also boasts the cute nicknames of Izzy — now shared, however, with a bevy of Isabellas — and Ike.
