Are you looking for a classic, biblical, traditionally masculine name that goes back to the Bible? Isaac may be the perfect choice for you.

Derived from the Hebrew יִצְחָק (Yitzhak), the name Isaac means “one who laughs” or “one who rejoices.” In the Old Testament of the Bible, Isaac is the firstborn son of Abraham. He is one of the three biblical patriarchs revered by Jews, Christians, and Muslims.

  • Origin: In the ancient Greek translation of the Bible, the Hebrew name Yitzhak was rendered as Isaak. This became Isaac in Latin, and then in English.
  • Gender: Isaac is traditionally a masculine name.
  • Pronunciation: EYE-zik

Although baby names are often separated by gender, Verywell Family believes that sex does not need to play a role in your name selection process. It’s important to select the name that you feel suits your new baby the best.

How Popular Is the Name Isaac?

A popular name in the early 20th century, Isaac lost favor for several decades before making a recent comeback. It rejoined the top 100 in 1995 and has remained there ever since, climbing to No. 28 in 2013 and coming in at No. 39 in 2020.

Although the name Isaac is typically used as a masculine name, it can certainly be used however you see fit, as sex doesn't have to be a part of your name selection process.
