I want to know the answer to the following question:
Who argued that the Old East Slavic Slavuta for the Dnieper River was derived from slova?
All the background I'm provided with is that "Lozinski argues that the word *slava once had the meaning of worshipper, in this context meaning "practicer of a common Slavic religion," and from that evolved into an ethnonym.". Is that enough to answer the question?
Answer: no
