Accommodation and Language Contact.

The paper introduces the Special Issue on , which originates from the conference Phonetics and Phonology in Europe (PaPE) held at the University of Lecce, Italy, in 2019. It discusses the topics of language contact and speaker accommodation, summarizing the contributions included in the Special Issue, and arguing explicitly in favour of a unitary view of how both temporary and stable changes happen in (part of) the linguistic systems. Accommodation is seen as the same gradual and non-homogeneous process at play in different contact settings.
