Korean is a language that people in Korea speak. If someone is from another country and wants to learn Korean, they would learn it as a foreign language.
Learning Korean as a foreign language means that you're learning it as something new and not something that you already know. It's like if you were given a new toy to play with, you would have to figure out how to use it by exploring it and trying different things.
When someone is learning Korean as a foreign language, they start by learning the basics. This includes the sounds of the language and how to say simple things like "hello" and "goodbye." As they get better, they will start to learn more complicated things like grammar and vocabulary.
To learn Korean as a foreign language, people use different methods like books, audio lessons, or videos. They also practice what they've learned by speaking with other people who speak Korean or by writing in Korean.
It takes a lot of practice and time to become really good at speaking Korean as a foreign language. But the good news is that once you can speak it, you can talk to lots of new people who speak Korean and learn more about their culture and way of life.
