Korean belongs to the Koreanic language group and is mostly isolated to the Korean Peninsula in Eastern Asia. It has roughly 80 million speakers and is an official language in two countries: The Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). Korean as a foreign language has grown in popularity in recent years, which Korean authorities attribute to an interest in Korean K-Pop music. South Korea has also become a popular place for native English speakers to teach English because of high demand, reasonable pay, and good living conditions. Korean as a whole is considered one of the most challenging languages for native English speakers to learn but the writing system (Hangul) is relatively simple and can be learned fairly quickly.
