I want to know the answer to the following question:
The Byzantine Greek σκλάβος sklábos "slave," which was in turn apparently derived from what?
All the background I'm provided with is that "The English word Slav could be derived from the Middle English word sclave, which was borrowed from Medieval Latin sclavus or slavus, itself a borrowing and Byzantine Greek σκλάβος sklábos "slave," which was in turn apparently derived from a misunderstanding of the Slavic autonym (denoting a speaker of their own languages).". Is that enough to answer the question?
