Balts
The Balts or Baltic people (Lithuanian: baltai, Latvian: balti) are an Indo-European ethno-linguistic group who speak the Baltic languages, a branch of the Indo-European language family, which was originally spoken by tribes living in area east of Jutland peninsula in the west and Moscow, Oka and Volga rivers basins in the east. One of the features of Baltic languages is the number of conservative or archaic features retained. Among the Baltic peoples are modern Lithuanians, Latvians (including Latgalians) — all Eastern Balts — as well as the Old Prussians, Yotvingians and Galindians — the Western Balts — whose people also survived, but their languages and cultures are now extinct.
Etymology
Adam of Bremen in the latter part of the 11th century AD was the first writer to use the term Baltic in its modern sense to mean the sea of that name. Although he must have been familiar with the ancient name, Balcia, meaning a supposed island in the Baltic Sea, and although he may have been aware of the Baltic words containing the stem balt-, "white", as "swamp", he reports that he followed the local use of balticus from baelt ("belt") because the sea stretches to the east "in modum baltei" ("in the manner of a belt"). This is the first reference to "the Baltic or Barbarian Sea, a day's journey from Hamburg."
