ENThis article has three goals. First, it provides a broad cross-linguistic survey of phonological change in contact situations focusing on the suprasegmental domain. The term suprasegmental refers here to syllable structure, stress patterns, tonal patterns, and vowel and nasal harmony systems. Secondly, it assesses phonological change to suprasegmental variables whereby external influence causes an increase in complexity in the recipient language’s structure. Thirdly, using insights from the phonological typology literature, it provides a preliminary framework to evaluate suprasegmental phenomena, which can then serve as an additional tool to disentangle inheritance from contact-induced change. Data from 45 languages suggest that the suprasegmental domain provides fertile ground for inspecting contact-influenced increases in linguistic complexity. Overall, we argue that the data reviewed here highlight the relevance of phonological structure as a variable in studies of language contact, which have been mostly preoccupied with morphosyntactic variables. Keywords: phonology; complexity; suprasegmentals; syllable structure; stress systems; tones. [From the publication]
