Hi Zerox There are thousands of such words in English. The words the Vikings brought to the language are usually everyday words that common people used, as opposed to the words derived from French during the Norman period. I am not familiar with Danish but the following words, for example, have a Scandinavian origin: winter (Swedish vinter), summer (sommar), give (giva, ge), take (taga, ta), they (de), bread (bröd), window (vind öga = eye of wind), father, mother, tree, life, folk, dale (dal), come, hear, full, wise, grey/gray, green, north, west, over, under etc.
