A false etymology (fake etymology or pseudo-etymology) is a false theory about the origin or derivation of a specific word or phrase. When a false etymology becomes a popular belief in a cultural/linguistic community, it is a folk etymology (or popular etymology).[1] Nevertheless, folk/popular etymology may also refer to the process by which a word or phrase is changed because of a popular false etymology. To disambiguate the usage of the term "folk/popular etymology", Ghil'ad Zuckermann proposes a clear-cut distinction between the derivational-only popular etymology (DOPE) and the generative popular etymology (GPE): the DOPE refers to a popular false etymology involving no neologization, and the GPE refers to neologization generated by a popular false etymology.[2]
Such etymologies often have the feel of urban legends and can be more colorful and fanciful than the typical etymologies found in dictionaries, often involving stories of unusual practices in particular subcultures (e.g. Oxford students from non-noble families being supposedly forced to write sine nobilitate by their name, soon abbreviated to s.nob., hence the word snob).[3][4]
