Izaak is a distinctive variant spelling of Isaac, a name with deep biblical roots.

While Isaac has remained a top-50 mainstay for decades, the Izaak spelling offers a more unique twist, appealing to parents who appreciate the traditional meaning and sound but want a less common variant. The name carries the same joyful etymology as Isaac, derived from the Hebrew Yitzchak, 'he will laugh,' and is used widely across cultures with slight variations.
