Book excerpt: The Role of Corpus Linguistics in the Ethnography of a Closed Community analyses the interactions of immigrants within an Irish reception centre for asylum seekers to highlight the instinctive resourcefulness of people who are faced with the challenge of communicating when there is no common language or culture. Based on three years of ethnographical observation and using an illuminating and innovative blending of applied methodologies, chiefly corpus linguistics, ethnography and conversation analysis, this book: Draws upon a corpus of 98,000 words; Examines the use of English in the interactions of residents with one another and those with English speaking staff of the centre; Challenges constructs such as speech community, communicative competence and interlanguage. This book is essential reading for academics and upper-level undergraduates or graduates working in the areas of Corpus Linguistics and Applied Linguistics, and those interested in research methodologies. It will also prove to be of significant interest to people interested in migration studies and to providers of English language education to immigrants.
