... It was already observed, that an absurd pronunciation has long prevailed relative to the name of the Sclavonian nations.  The name is formed from slava, a term signifying glorious, adopted by the people themselves, in allusion to some signal but now unknown success in battle.  Hence many proper names, in countries where the Sclavonian is spoken, contain the term.  Thus Stanislavus, corrupted into Stanislaus, denotes a person who stands firm for glory; Radoslavus, one who labours for glory; Vladislavus, one who reigns with glory.  From this circumstance it has been inferred, that the proper name of the nation was Slava; and if we sometimes meet with Slova and Slovinska, the variation arises from the practice of certain districts, where o is substituted for a in many other words.  Besides these names having peculiar meanings, many others are found in Russia, Poland, &c. formed from terms significant in Sclavonian.  Thus we find Radimir, the maker of peace; Zuonimir, the herald of peace; Cascimir, improperly Casimir, the declarer of peace; Budimir, the imposer of peace.
