The ウラル・アルタイ語族 (Ural-Altaic language family) is a proposed grouping of languages that includes the ウラル語族 (Uralic languages) and the アルタイ語族 (Altaic languages). The Uralic languages consist of languages like フィンランド語 (Finnish) and ハンガリー語 (Hungarian), while the Altaic languages include トルコ語 (Turkish) and モンゴル語 (Mongolian). Linguists have debated the validity of the Ural-Altaic classification, as some argue that the similarities between these languages may be due to language contact rather than a common origin. Despite this, the study of the Ural-Altaic languages provides insights into the historical and cultural connections among the peoples who speak them.
