Isaac

Isaac is a Hebrew name derived from the root meaning he laughs or he will laugh, reflecting the laughter of both Abraham and Sarah upon learning they would have a child in old age. In the Hebrew Bible, Isaac is the son of Abraham and Sarah and a patriarch of the Israelite people, making the name deeply significant in Jewish, Christian, and Islamic traditions. The name passed into Greek as Isaak and Latin as Isaacus, spreading widely through Europe during and after the medieval period. Variant forms include Isaak, used in German, Russian, and Scandinavian traditions, as well as the Spanish and Portuguese Isac and the anglicized form Ike as a familiar diminutive.
