What does the word Viking mean?

I have often come across people who are telling me, that it is not correct to use the word Viking for all the people who lived in Scandinavia during the Viking age. Most people claim that it was only those who went on raids that were Vikings, as in ”to go Viking”. Others say they came from Viken in Norway, or the from the villages named Vik. So what does the word Viking really mean? And do we have some sources to look at that can help us understand this word. This is what we are going to explore today.
