The Korean language, known as Hangul, is the official language of both South Korea and North Korea. It is a unique language that uses a phonetic alphabet, which was created in the 15th century by King Sejong the Great. Hangul consists of 14 basic consonants and 10 basic vowels, allowing for the formation of syllables and words. Korean is classified as a language isolate, meaning it has no close relation to other language families. It is primarily spoken by around 80 million people worldwide. The language has a rich history and is influenced by Chinese and Japanese, particularly in vocabulary and writing systems.
