The story behind Isaac
From Middle English Ysaac, from Latin Isaac, from Ancient Greek Ἰσαάκ (Isaák), from Hebrew יצחק (Yiṣḥāq, literally “he laughs, he will laugh”). Explained in Genesis as referring to his mother Sarah’s laughing when she was told she would have a son at her old age. The verb is masculine, however, perhaps due to its use as a boy’s name.
