Epistemological psychology
The term episteme is related to the Greek word επιστήμη, which translates literally as "standing near or by that which causes" but is often simplified as "knowledge" or "science". By ignoring ego interests the core impetus or the essence of a deed, real or imagined, is recovered.
Folk etymology
The technical term "folk etymology" refers to a change in the form of a word caused by erroneous popular beliefs about its etymology. The English word is a translation of the German term "Volksetymologie", coined by Ernst Förstemann. Förstemann noted that in addition to scientific etymology based on careful study in philology, there exist scholarly but often unsystematic accounts, as well as popular accounts for the history of linguistic forms. Until academic linguists developed comparative philology and described the laws underlying sound changes, the derivation of words was a matter mostly of guess-work. Speculation about the original form of words in turn feeds back into the development of the word and thus becomes a part of a new etymology.
