The origin of the Slavic autonym is disputed. • According to
Roman Jakobson's opinion, modified by
Oleg Trubachev and John P. Maher, the name is related to the
Proto-Indo-European (PIE) root seen in
slovo ('word') and originally denoted "people who speak (the same language)", i.e. people who understand each other. The word
slovo and the related
slava ('glory, fame, praise') and ('hearing') originate from the PIE root ('be spoken of, glory'), cognate with Ancient Greek ( 'fame'), whence comes the name
Pericles, Latin ('be called'), as well as English . • Another widely cited view is expressed by
Max Vasmer, who points out that the suffix Proto-Slavic , otherwise seems to derive nouns only from
toponyms; hence Vasmer assumes that this word, too, is derived from a toponym - probably a hydronym, comparable to various Slavic river names with the same apparent root such as Russian Слуя, Polish , ,
Serbo-Croatian (), further related to Ancient Greek (, 'lave'), (, 'flow'), (, 'surf, rough water'), Latin ('to clean'), ('sewer pipe'). According to this view, the connection to ('word') would be the result of a later
folk etymology. It has been suggested that the word may be derived from a place named
Slovo or a river named
Slova; this, according to some, is implied by the suffix . The
Old East Slavic () for the
Dnieper River was argued by Henrich Bartek (1907–1986) to be derived from and also the origin of . However, this name of the Dnieper River is only attested in the 17th century. • Based on an uncertain S. B. Bernstein speculated that it derives from a reconstructed
Proto-Indo-European , cognate to
Ancient Greek (; 'population, people'), which itself has no commonly accepted etymology. According to the widespread view, which has been known since the 18th century, the Byzantine (), (), borrowed from a Slavic tribe self-name *Slověne, turned into , (
Late Latin sclāvus) in the meaning 'prisoner of war slave', 'slave' in the 8th/9th century, because they often became captured and enslaved. However this version has been disputed since the 19th century. An alternative contemporary hypothesis states that
Medieval Latin via secondary form derives from Byzantine (, ) or (, ) with the meaning 'to strip the enemy (killed in a battle), to make booty, extract
spoils of war'. This version is criticised as well. == See also ==
