newlywed (n.)

also newly-wed, 1907, from newly + wed. Probably owes its origin to a then-popular newspaper comic strip, "The Newlyweds and Their Baby," about Mr. and Mrs. Newlywed, by George McManus in the New York "World." As an adjective, newly-wed is attested from 1833. An earlier adjective was new-married (1530s). Ancient Greek had neo-zygos "newly married," literally "newly yoked."
