That is not true at all. The Word Slav comes from the word Slava. From what I've heard...the word slave comes from Slav. Because so many Slavs were kidnapped by Viking slave traders and sold into slavery back in the day. The Vikings used to be notorious slave traders, they had extensive slave trading networks all over Europe and into the middle east, the Slavs were their favorite victims, they would terrorize and kidnap Slavic peasants by the hundreds and sell them into slavery in places like Greece and Byzantium/the middle east. The word Slav became synonymous with slave because there were so many of them. I watched an interesting tv program all about that before, not too very long ago, about the Vikings being notorious slave traders and such and kidnapping and selling so many Slavs. The word Slav doesn't come from slave, it's the other way around from what I know.
