Meaning & Origin
Yitzchok is a boy's baby name of Hebrew origin, the Yiddish form of Isaac, from the Hebrew Yitzhak meaning "he laughs" or "laughter," so named because Abraham and Sarah both laughed in disbelief at being promised a son in old age. In the Bible, Isaac was the son miraculously born to Abraham and Sarah.
Yitzchok is used exclusively within Orthodox and Hasidic Jewish communities in the United States, representing the traditional Yiddish pronunciation of this foundational biblical name. It maintains the ancient Hebrew name's exact meaning while reflecting centuries of Eastern European Jewish tradition.
