The Scandinavian word for honeymoon is derived, in part, from an ancient Northern European custom in which newlyweds, for the first month of their married life, drank a daily cup of honeyed wine called mead. The ancient practices of kidnaping of bride and drinking the honeyed wine date back to the history of Atilla, king of the Asiatic Huns from A.D. 433 to A.D. 453.
So that leaves us with the question of where the "moon" in the word "honeymoon" originates. One piece of folklore relates that the origin of the word moon comes from a cynical inference. To the Northern Europeans the terms referred to the body's monthly cycle and, its combination with honey, suggested that not all moon's of married life were as sweet as the first. British prose writers and poets, in the 16th and 17th centuries, often made use of the Nordic interpretation of honeymoon as a waxing and waning of marital affection.
