Old English was more clearly influenced by Old Norse. Scandinavian loan words in English include place names, items of basic vocabulary such as "sky", "leg" and "they", and words concerned with particular administrative aspects of the Danelaw (that is, the area of land under Viking control, including the East Midlands and Northumbria south of the Tees). Old Norse was related to Old English, as both originated from Proto-Germanic, and many linguists believe that the loss of inflectional endings in Old English was accelerated by contact with Norse.
