Word Origins: Good-Bye


The word “Good-bye” is actually derived from the words God be with you.  Its first recorded use is in a 1573 letter.  Earlier forms of God be with you were: God be wy you, godbwye, god bwy ye, and good-b’wy (Shakespeare used  God be wy you and God buy’ ye). The word did not reach its modern form goodbye until the 18th century. The substitution of good for God seems to have been mainly due to the influence of such phrases as good day and good night.
