The paper presents the cases of folk etymology in the Hungarian family name stock. It deals with possibilities and difficulties in the interpretation of the term, as well as the differences in the use of the term between the traditional international and Hungarian linguistics. It also examines the issue of learned folk etymologies or naive etymologies as part of folk etymology with some examples from the 13th century. The paper argues that communal associations, analogies and approval play an essential role in folk etymological changes and this should be taken into consideration in the study of the phenomena. It presents examples of changes within the Hungarian language and of changes in interlingual connections throughout the latest centuries in the Carpathian Basin. Also, it introduces the case of hidden folk etymology with examples of name Magyarizations.
