Isaac: Meaning, origin and popularity
Pronounced EYE-zuhk · 2 syllables
Isaac means “he will laugh”, from Hebrew.
From Middle English Ysaac, from Latin Isaac, from Ancient Greek (Isaak), from Hebrew (Yishaq, 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.
