Meaning & Origin
Isaac (biblical character)
Isak is a boy's baby name, the Scandinavian and Baltic form of Isaac, from Hebrew meaning 'he will laugh' or 'laughter.' Isak is the spelling used in Sweden, Norway, Denmark, Finland, and Estonia — a name deeply embedded in Nordic culture while sharing its biblical roots with the English Isaac.
Isak Dinesen — pen name of Karen Blixen, the Danish author of Out of Africa — brought this spelling to literary attention. It has a clean, Nordic simplicity that sits beautifully in the contemporary naming landscape.
