Korean is the official language of South and North Korea. It is also one of the two official languages in the Yanbian Korean Autonomous Prefecture in China. There are about 78 million Korean speakers.
Unlike most of the European languages, Korean does not conjugate verbs using agreement with the subject, and nouns have no gender. Instead, verb conjugations depend upon the verb tense, aspect, mood, and the social relation between the speaker, the subjects, and the listeners.
