What’s the origin and meaning of the name Isaac?

Isaac is a biblical name of Hebrew origin that in its original version is spelled Yishaq’el. It’s believed to be derived from the word tzachaq, which means “to laugh”.

The story of the meaning of this name is very beautiful and is found in the Bible. Isaac was born from the union of Abraham, who was 100 years old, and Sarah, who was 90 when she gave birth to him. For this reason, the name of this son is related to the joy, laughter, and disbelief of this very special event.

Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” And Abraham said to God, “If only Ishmael might live under your blessing!” Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him.”

– Genesis 17:17-19, The Bible –

Over time, the meaning of Isaac was interpreted more broadly. Thus, today it’s known as “the one who laughs” or “the one with whom God will laugh”. In any case, this name is related to the joy and happiness of birth.
