This volume brings together a number of corpus- based studies dealing with language varieties. These contributions focus on contemporary lines of research interests, and include language teaching and learning, translation, domain-specific grammatical and textual phenomena, linguistic variation and gender, among others. Corpora used in these studies range from highly specialized texts, including earlier scientific texts, to regional varieties. Under the umbrella of corpus linguistics, scholars also apply other distinct methodological approaches to their data in order to offer new insights into old and new topics in linguistics and applied linguistics. Another important contribution of this book lies in the obvious didactic implications of the results obtained in the individual chapters for domain-based language teaching.
