Purist language policies in Iceland have preserved and modernized Icelandic up until the present time. However, the impact of globalization and global English has led to the perception that the language is less secure than in the past and has prompted efforts by policy makers towards greater protection of Icelandic. This monograph presents the current language profile of Iceland, along with the history of Icelandic and the language ideologies underpinning it, which have led up to present day language planning efforts: in corpus planning and some domains of status planning such as education and the media. The monograph discusses the impact of supranational language policies upon Iceland's language planning, the role of the media in language spread, as well as current trends in the domain of higher education. Furthermore, the authors explore whether Icelandic can be maintained as the sole language of Iceland. (Contains 4 figures, 9 tables, and 17 notes.)
