The Koreanic language family primarily consists of the Korean language, which is spoken in both South Korea and North Korea. It is characterized by its unique writing system, Hangul, created in the 15th century. The language has various dialects, with the standard dialect based on the speech of Seoul. Some linguists debate whether Koreanic is a language isolate or related to other language families, such as the Altaic languages. Despite these discussions, the Koreanic family remains distinct, with its own grammatical structure and vocabulary, reflecting the rich cultural history of the Korean Peninsula.
