This study examines the use of English in Switzerland from a multilingual perspective based on a corpus of 400 interviews collected in the German speaking Canton of Zurich. It presents a framework for explaining the linguistic interaction that arises as a result of the use of a -globalizing- language in a multilingual context. It has given the relationships that obtain between the various Swiss national languages a hierarchical character. The proposed Swiss framework indicates - viewed through a macro-sociolinguistic lens - that the present linguistic situation in Switzerland seems to reflect a growing symbiotic relationship between English and the Swiss vernaculars."
