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.
