The present article analyzes the Vilamovicean language within the framework of language contact. The author studies various sociolinguistic, lexical and grammatical features and properties, which are typical of mixed languages, and which can be found in Vilamovicean. The evidence suggests that Vilamovicean can be defined as a mixed German(ic)-Polish language, relatively advanced on the cline(s) of mixing. Although Vilamovicean originated as an exemplary member of the German(ic) family – and although the bulk of its components are still German(ic) – due to prolonged and intense contact with Polish, the ethnolect became similar to this Slavic language.

The success rate of authorship attribution by multivariate analysis of most-frequent-word frequencies is studied in a 1000-novel corpus of Polish literary works from the late 18th to the early 21st century. The results are examined for possible influences of the number of authors and/or the number of texts to be attributed. Also, the success rates achieved in this study are compared to those obtained in earlier studies for smaller corpora, too small perhaps to produce regular patterns. This study shows that text sets of this size confirm the intuitive predictions as to those influences: 1) the more authors, the less successful attribution; 2) for the same number of authors, the number of texts to be attributed does not influence success rate.
