Meaning and origin

Isaac means "He laughs" / "he will laugh, he will rejoice" -- the Genesis text explicitly explains the name via Abraham's and Sarah's laughter at the news of a child born to them in old age.

During the medieval period Isaac was used only occasionally among English Christians but was considerably more common among Jews; its use among English Christians expanded significantly after the Protestant Reformation's turn toward Old Testament naming.
