Originating from Hebrew, the name Isaac is derived from the Semitic root 'sákh,' meaning 'he will laugh.' It was borne by the patriarch Isaac in the Bible, who was the son of Abraham and Sarah, born to them in their old age after Sarah had laughed at the prospect of having a child. The name gained prominence through the biblical story and has since been widely used across various cultures.
The name Issak experienced notable fluctuations in popularity over the years, with a significant peak between 2000 and 2007, and a steady decline thereafter.
