The
Koreanic languages is a
language family consisting of the modern
Korean language together with extinct ancient relatives closer to it than to any proposed links with
Mongolic,
Turkic,
Tungusic, or
Japanese. Among extant languages, Korean is considered by most linguists to be a
language isolate, and by others as part of the widely rejected
Altaic family. The
Jeju language of
Jeju Island, considered by some as a dialect of modern Korean, is distinct enough to be considered a language in its own right by other authorities. Some consider that rather than being a language isolate, Korean forms a small language family together with Jeju.
