Isaack

Isaack is a given name, a historical or less common variant of Isaac. The name derives from the Hebrew Yitzhak, meaning "laughter" or "he will laugh," and it appears in the Bible as the son of Abraham.

Spelling variants include Izaak and Isaak, common in Dutch, Afrikaans, and German contexts, as well as the English form Isaac. The spelling Isaack with a ck is comparatively rare today and is typically found in older English records or genealogical sources, reflecting historical orthography rather than a distinct modern name.

Usage of Isaack mirrors that of Isaac, with adoption across Christian and Jewish communities in Europe and beyond. The name is more often encountered in historical records or as part of family names rather than as a widely used contemporary given name.

Notable people bearing this exact spelling are not widely documented in major reference works; individuals with this spelling may appear in genealogical material or regional histories.
