バルト・フィン諸語
The Southern Finnic languages consist of North and South Estonian (excluding the Coastal Estonian dialect group), Livonian and Votic (except the highly Ingrian-influenced Kukkuzi Votic). These languages are not closely related genetically, as noted above; it is a paraphyletic grouping, consisting of all Finnic languages except the Northern Finnic languages. The languages regardless share a number of features, such as the presence of a ninth vowel phoneme "õ", usually a close-mid back unrounded (but a close central unrounded in Livonian), as well as loss of "*n" before "*s" with compensatory lengthening.
