Meaning & Origin
Izaac is a boy's baby name, an alternate spelling of Isaac, of Hebrew origin, meaning 'he will laugh' or 'laughter' — from the Hebrew Yitzchak. In the Bible, Isaac was the son miraculously born to the elderly Abraham and Sarah, and his mother's joyful laughter at the news gave him his name.
Isaac has been one of the most consistently used Hebrew names in the English-speaking world for centuries, ranking in the American top 50 for years. Izaac's alternate spelling gives the classic a more unusual visual identity while keeping the beloved sound. Parents who love the name but want a slightly more distinctive form often gravitate toward this spelling.
