South Slavic languages. It is thus a cognate of the words Slavonia, Slovakia, and Slavia. The etymology of itself remains uncertain. The reconstructed autonym is usually derived from the word slovo 'word', originally denoting 'people who speak (the same language)'; i.e., people who understand each other. This is in contrast to the Slavic word denoting German people, namely , meaning 'silent, mute people' (from Slavic 'mute, mumbling'). The word slovo 'word' and the related slava 'glory, fame' and slukh 'hearing' originate from the Proto-Indo-European root 'be spoken of, glory', cognate with Ancient Greek ( 'fame'), as in the name Pericles, Latin 'be called', and English . The modern Slovene state originates from the Slovene National Liberation Committee (SNOS) held on 19 February 1944. They officially named the state as Federal Slovenia (), a unit within the Yugoslav federation. On 20 February 1946, Federal Slovenia was renamed the People's Republic of Slovenia (Ljudska republika Slovenija). It retained this name until 9 April 1963, when its name was changed again, this time to the Socialist Republic of Slovenia (). On 8 March 1990, SR Slovenia removed the prefix "Socialist" from its name, becoming the Republic of Slovenia; it remained a part of the Socialist Federal Republic of Yugoslavia until 25 June 1991. History Prehistory to Slavic settlement Prehistory Present-day Slovenia has been inhabited since prehistoric times. There is evidence of human habitation from around 250,000 years ago. A pierced cave bear bone, dating from 43100 ± 700 BP, found in 1995 in Divje Babe cave near Cerkno, is considered a kind of flute, and possibly the oldest musical instrument discovered in the world. In the 1920s and 1930s, artifacts belonging to the Cro-Magnon, such as pierced bones, bone points, and a needle were found by archaeologist Srečko Brodar in Potok Cave. In 2002, remains of pile dwellings over 4,500 years old were discovered in the Ljubljana Marsh, now protected as a UNESCO World Heritage Site, along with the Ljubljana Marshes Wooden Wheel, the oldest wooden wheel in the world. It shows that wooden wheels appeared almost simultaneously in Mesopotamia and Europe. In the transition period between the Bronze Age to the Iron Age, the Urnfield culture flourished. Archaeological remains dating from the Hallstatt period have been found, particularly in southeastern Slovenia, among them a number of situlas in Novo Mesto, the "Town of Situlas".
