Interesting about Baltics
The term "Baltic" stems from the name of the Baltic Sea – a hydronym dating back to the 11th century (Adam of Bremen mentioned Latin: Mare Balticum) and earlier. Although there are several theories about its origin, most ultimately trace it to Indo-European root *bhel meaning white, fair. This meaning is retained in modern Baltic languages, where baltas (in Lithuanian) and balts (in Latvian) mean "white". However the modern names of the region and the sea, that originate from this root, were not used in either of the two languages prior to the 19th century.
