Korean is the official language of South Korea, spoken by more than 75 million people, of whom 48 million live in South Korea and 24 million in North Korea.
The Koreas differ in minor matters of spelling, alphabetization, and vocabulary choice but both essentially endorse the unified standards. Korean spelling is complicated.
Words are usually written in a morphophonemic manner rather than phonemically. Many people these days want to learn a new language and they choose Korean because of the popularity of Korean Dramas, movies, and culture.
