This entry reviews the history and contemporary functions and features of English in Sweden and shows that English has made great inroads into many aspects of Swedish society, such as education, as well as working and private life. Today all Swedes learn English and many also study through the medium of English and use English at work. English has a big presence in the linguistic landscape of Sweden and Swedes' leisure and entertainment activities. However, following the rapid spread of English in Sweden in the last few decades, debates have arisen focusing on the effect of English on Swedish and society as a whole. Nevertheless, although English is ubiquitous in Sweden, Sweden should still be considered an Expanding Circle country.
