Namenzwillinge und ‑mehrlinge in der Toponymie: Am Beispiel von Deutschschweizer Ortsnamen

Not all place names are unique, and certain place names are – or used to be – name twins or even name multiples. In a corpus of around 1200 place names from German speaking Switzerland it was found that nearly a quarter of them share the original name form with at least one other name (etymological or primary homonyms). Today, the originally identical name forms are either the same or differ from each other. A smaller part of the corpus consists of place names that show the same name form today but derive from different original name forms (secondary homonyms). This article explores the possibility of classifying place names according to the concept of homonymy, which is familiar primarily in relation to common nouns and has not been examined with regard to place names before. As a first step, the place names were classified into types of homonymy (total or partial homonymy). Subsequently, the processes that lead from the original name form to today’s name form – either parallel to or different from each other – were investigated and characterized. The aim was to explore the influencing factors affecting the development of the name forms. It was found that the geographical distance between the places involved can have a major influence on the development of the names. However, phonological processes, writing conventions in administration, morphology and folk etymology also play an important role
