Selonian was an East Baltic language, which was spoken by the East Baltic tribe of the Selonians, who until the 15th century lived in Selonia, a territory in southeastern Latvia and northeastern Lithuania.
[1] 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 northeastern sub-dialects of the Aukštaitian dialect of the Lithuanian language, mostly in the lexicon.
[citation needed] It is considered that the Selonian language retained the Proto-Baltic sonorant diphthongs *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.
