This book provides a linguistic and cultural profile of the Polish diasporic communities in three different European countries: Ireland, France and Austria. The eight contributing chapters present original research on the acquisition and use of the languages of the respective host communities and also explore related elements of cultural acquisition. A number of aspects of second language acquisition are considered, notably the acquisition of phonology, lexicon and discourse, as well as aspects of sociolinguistic competence. In addition, varying approaches and research methods are reported on, each of which was chosen in consideration of the particular research issue addressed and the particular circumstances under which the research was carried out. These range from psycholinguistic approaches to second language acquisition to variationist approaches, and include both quantitative and qualitative methodologies.
