Selonian was a Baltic language spoken by the Eastern Baltic tribe of the Selonians who until the 15th century lived in Selonia a territory in South Eastern Latvia and North Eastern Lithuania.During the 13th-15th centuries the Selonians lost their language after being assimilated by the Latgalians and partly by the Lithuanians.It is considered that the Selonian language retained the proto-Baltic phonemes *an *en *in *un like the Lithuanian language but like the Latvian language the proto-Baltic *kʲ *ɡʲ changed to c dz and the proto Baltic *š *ž changed to s z.Traces of the Selonian language can still be found in the territories the Selonians inhabited especially in the accent and phonetics of the so-called Selonian dialect of the Latvian language.There are some traces of the Selonian language in the North Eastern sub-dialects of the Aukštaitian dialect of Lithuanian language mostly in the lexicon.
