The Altaic language family is a proposed group of languages that includes several language branches, primarily Turkic, Mongolic, and Tungusic. These languages are spoken across a vast region, from Eastern Europe to Central Asia and Siberia. Linguists believe that these languages may share a common ancestral language, which is why they are grouped together. Some researchers also include the Korean and Japanese languages in the Altaic family, although this is a topic of debate among scholars. The similarities among these languages can be seen in their grammar and vocabulary, making the study of the Altaic family an interesting area in linguistics.
