摘要：This paper intends to show the importance of having linguistic instruments, principally semantic ones, for determining the meaning of words with the greatest precision and, consequently, managing to meticulously establish the different meanings of a dictionary's entry words. As an example, a new definition of the Spanish verb mezclar ('to mix') will b Since the beginning of the publication of the linguistic atlas of German-speaking Switzerland (Sprachatlas der deutschen Schweiz, SDS) in the early 1960s individual linguists collected contemporary material for comparison to investigate language change. However, due to time and money restrictions these studies were limited to small parts of the language area only. So far a description of tendencies concerning the entire Swiss German language area is missing. Based on an online-survey of 5600 informants this investigation is the first to present word geographic data covering (almost) the whole German-speaking Switzerland. Comparing GIS-maps of SDS and online data of the dialectal lexemes for freckles, onion and butterfly, language change over the last century becomes apparent, with striking convergence tendencies towards standard German, but also a Swiss German dialect expanding its range. Most of the dialect words mentioned in the SDS were preserved; some new were found. Thus, diversity of lexicon and creative language use are not endangered. Statistical analysis showed that younger speakers are more likely to deviate from the SDS. Less strong, but still significant were the influence of the parent's dialect and the duration of living in the dialect area, whereas gender had no influence.
