honeymoon

The story

From earlier hony moone, originally denoting the period of time following a wedding, equivalent to honey + moon. The original reference was to affection waning like the moon, but later the sense became "the first month, or moon after marriage", which tends to be the sweetest. Compare Middle Low German suckermânt (“honeymoon”, literally “sugar-month”), German Low German Hönnigweken (“honeymoon”, literally “honey-weeks”). The German Honigmond (literally “honey-moon”) is a calque of French lune de miel, itself a calque of the English term.
