This article discusses the nature of the attrition of the Arbresh dialect of Piana degli Albanesi. It investigates the state of language use, the state of structural decay, and the linguistic attitude of Arbresh speakers. It concludes that this Arbresh dialect is undergoing a process of “dysfunctional attrition,” which consists of a progressive shrinkage of linguistic domains and functions, a decrease in the number of speakers, and a decline in linguistic competence as the speakers’ age diminishes. Unlike previous views, it maintains that dysfunctional attrition is not necessarily characterized by stigmatization and rejection of the language. The study emphasizes that a positive attitude towards the language is not a guarantee of linguistic survival, and that other aspects of language deterioration and loss must not be neglected in the process of linguistic revitalization.
