Master's Thesis from the year 2017 in the subject Didactics for the subject English - Miscellaneous, grade: Distinction: 9/10, University of Jaén, language: English, abstract: This dissertation aims at explaining the enormous impact of Old Norse on the English language, more prominent in quality than in quantity. Such influence is firstly dealt with by focusing on the historical and sociocultural context, which, split into different periods, becomes of paramount importance in order to grasp the essence of such contact, both linguistic and cultural, between both societies throughout the centuries. Linguistically, general features of the Germanic group of languages are approached from different perspectives, mainly from the phonetical and morphosyntactic ones. Likewise, such analysis is followed by a comparative one between Old Norse and Old English as coexisting languages, thus allowing similarities and differences between both of them to come to the fore. Finally, the Old Norse influence is covered by taking into special account morphosyntactic and lexical elements, that is, those areas where both Germanic languages have come closer to each other. Therefore, this has allowed us to delve into those numerous items stemming either from the same or from dissimilar sources, most of which, whatever the case, are still substantially present in the everyday uses of today’s English.
