Native and foreign language competences constitute a widespread object of study among different scholars both in more theoretically oriented frameworks within general linguistics and in applied linguistics such as second language acquisition research. This book shows how language competences can be understood from different perspectives. The eight chapters in this book treat various dimensions of language competences and different aspects of English, German, and Spanish. The aim is to provide some answers to the often raised questions regarding language competence in practical as well as principled ways and to provide new angles on these competences in areas such as general linguistics, business communications, legal language, and within the service sector. The authors have worked within the foreign language and linguistic field for many years, making substantial contributions through the publication and dissemination of research in international journals and with international publishers. This volume is aimed at readers (scholars, students and professionals alike) who take an interest in language competences. The book thus offers a broad view on native and foreign language competences and the various facets of these concepts that are reflected in our multicultural and multilingual societies.
