Meaning & Origin
A male given name from Hebrew.
Yitzchak is a boy's baby name of Hebrew origin, the authentic Hebrew form of Isaac, meaning 'he laughs' or 'laughter.' When Sarah heard she would bear a son in old age, she laughed — and the child's name captured that moment of joyful disbelief made real. Yitzchak is used in traditional Jewish communities as the most authentic form of this biblical patriarch's name.
