Meaning & Origin
a male given name
Isac is a boy's baby name, a Scandinavian and Portuguese variant of Isaac, from Hebrew Yitzchak meaning 'he will laugh' or 'laughter.' Isaac was the miraculous son of Abraham and Sarah in the Old Testament, born when his parents were very old — his name commemorates Sarah's laughter of disbelief and joy.
The Isac spelling is commonly used in Sweden, Norway, and Brazil, giving this ancient biblical name a fresh, international character. A name whose meaning — laughter — carries an inherent lightness and joy.
