List of common misconceptions
The word 'fuck' did not come from Christianized Anglo-Saxon England and it is not any kind of acronym. The earliest recorded use of 'fuck' in English comes from about 1475, in the poem Flen flyys, where it is spelled fuccant (conjugated as if a Latin verb, meaning 'they fuck'). It is of Proto-Germanic origin, and is related to Dutch fokken and Norwegian fukka. Modern English was not spoken until the 16th century, and words such as 'fornication' did not exist in any form in English until the influence of Anglo-Norman in the late 12th century.
