The Theory of Linguistic Adaptation has been attracting extensive academic attention，and related studies have been fruitful, yet as Jef Verschueren, the initiator of the theory, points out, its operationality and basic concepts are being misinterpreted. This interview investigates the background of its proposal, discusses the difference between “adaptation” and “adaptability”, analyses the operationality of linguistic adaptation and puts forward the issues of anti-adaptation and negative adaptation. While reporting interview, the authors comment accordingly on related arguments, summarize and propose that a combination of philosophical cogitation and operational application can enrich the theory, and more importantly provides a clearer exploring approach and sounder theoretical support.
