It was spoken in the northern part of Lithuania and southern regions of Latvia in what is known as Semigallia. It is thought that it was extinct by the 16th century, with the assimilation by the Latvians.[1] Semigallian is known only from references to it in documents and texts from before the 16th century.
Phonology
Semigallian shares some phonological similarities to Curonian and, to a lesser extent, Latvian. The Common Baltic /k/, /ɡ/ consonants became /c/, /d͡z/ in their soft varieties in Semigalian. All long vowels and diphthongs at the end of the word in Common Baltic were reduced to simple short vowels in Semigallian.[2]
