This paper focuses on two heritage communities of Bernese Swiss German in terms of linguistic maintenance with respect to a subset of the lexicon and Bernese-specific phonological phenomena. An aim is to contribute to the discussion of linguistic change observed in two sets of unrelated languages (here: Bernese-English and Bernese-Spanish). The results suggest that the heritage languages diverge to differing degrees in one of the phenomena and pattern alike in another, but likely do so independently of their respective contact languages.
