Meaning & Origin
A male given name from Hebrew.
Issac is a boy's and girl's baby name of Hebrew origin, a variant spelling of Isaac, from the Hebrew Yitzhak meaning "he laughs" or "laughter," so named because his elderly mother Sarah laughed in disbelief when told she would bear a son. In the Bible, Isaac was the son of Abraham and Sarah.
The Issac spelling is an alternate form that has recorded nearly 25,000 U.S. births in its own right. While less common than the standard Isaac, it represents the same great patriarchal name — carrying the joy of unexpected blessings and divine humor.
