Forget all the myths about the groom or sometimes the bride and groom drinking honeyed mead for the first month of their marriage to ensure fertility. This is spurious folk etymology. Honeymoon, which makes its appearance into the language during the 16th century, simply means the honey or sweet month, the first month of a marriage. The word moon and month derive from the same Old English root, a month being a measure of time corresponding to one revolution of moon. Now, of course honeymoon means the holiday spent together by a newly married couple.
