What does the name Isaac mean?

The meaning of the name “Isaac” is: “Laughter; the laughing one;”.

Additional information: Isaac is a masculine name from the Hebrew Yitzchak that means ‘he laughs’, and it is the name of the son of Abraham and Sarah, the husband of Rebecca and the father of Jacob and Esau in the Old Testament. Sarah could not bear children and was already very aged at the time of his conception. She chose the name Isaac because she had laughed at the messengers of God announcing that she would finally have a son.

The name was more common among Jewish people until the Protestant Reformation, when biblical names such as Isaac, Joshua, and Noah became much more widespread. As a Hebrew name it has other Hebrew variants because of the different ways to Anglicise its spelling – Itzhak and Yitzchak are two alternative ways to spell Isaac. The name Sarina is a feminine Hebrew name that means ‘One Who Laughs’, making it a suitable alternative for Isaac. Common nicknames for Isaac are Ike, Ise, Izzy, and Sekel, and foreign language variants include Sahak (Armenian), Isaak (German), and Izsák (Hungarian). Isaac is sometimes misspelled as ‘Issac’, ‘Isac’, and ‘Isacc’.
