Gender: Male Meaning of Isaac: "laughter" Origin of Isaac: Hebrew Isaac's Popularity in 2019: #34

Isaac Origin and Meaning

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

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.

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 went on to assume something of a rabbinical image.

A baby given this name can point to many distinguished namesakes, including Isaacs (and Izaaks) Newton, Walton, Bashevis Singer, Asimov, Stern and Hayes. The name was somewhat rejuvenated by onetime heartthrob Isaac Hanson.

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

I love this name, because of its unique spelling but familiarity. Kinda like the name Ephraim. Love names like this :)

headintheclouds Says:


I think this is one of the nicer biblical names (there are some that I can't stand, like Aaron and Deborah). IMO it has a classic vibe with a double side; it can also sound more cool/retro/hipster, something like Levi and Abram (versus the more classic-everyday biblical names like Ethan and Hannah).
