From Latin Balticus, from Latin Balthae (“dwellers near the Baltic sea”), equivalent to Balt + -ic. The ultimate origin is uncertain, but possibilities include: From North Germanic baltaz (“strait”), in reference to the narrow entranceway of the sea. This word itself could be borrowed from Lithuanian baltas (“white”) or related to Proto-Germanic *baltijaz (“belt”) (see below). Related to Lithuanian baltas (“white”) and Proto-Slavic bolto (“swamp, bog, mud”), which are from Proto-Indo-European *bʰel- (“white”). Related to Latin balteus (“belt”) (compare Proto-Germanic baltijaz), referring to the Danish straits, "the Belts". This is suggested by Adam of Bremen, who in the 11th century first recorded the name (Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam). More at Baltic.
