In Lithuanian, besides ''Baltarusija'' (White Russia), Belarus is also called ''Gudija''. The etymology of the word ''Gudija'' is not clear. By one of the hypothesis the word derives from the Old Prussian name ''Gudwa'', which, in turn, is related to the form ''Żudwa'', which is a distorted version of ''Sudwa, Sudovia. Sudovia'', in its turn, is one of the names of Yotvingians. Another hypothesis connects the word with Gothic Kingdom that occupied parts of territory of modern Belarus and Ukraine in 4th and 5th centuries. The self-naming of Goths was ''Gutans'' and ''Gytos'' which are close to Gudija. Yet another hypothesis is based on the idea that ''Gudija'' in Lithuanian means "the other" and may have been used historically by Lithuanians to refer to any people who did not speak Lithuanian.
