What does the name Izak mean?
Izak is a spelling of Isaac, pronounced the same way, so it shares Isaac's meaning and origin.
Isaac is the Hebrew Yitzhak, 'he laughs' or 'he will laugh'. In Genesis he is the son of Abraham and Sarah, and his name recalls Sarah's laughter at being promised a son in old age. In Genesis 21:6 Sarah says that God has brought her laughter. Medieval Christian and Jewish communities both used the name; DMNES finds it in England from 1222.
