No, Korean and Korean are essentially different. Korean is like what Koreans in North Korea and China say, and Korean is what South Korea says. After years of changes, Korean has merged many foreign words, just like tomatoes? It's Tomato in English, not in Korean, and there are new words, such as Lengdu male and Jing Daole female. It depends on whether Korean majors in universities are merged with Korean, such as whether loanwords and neologisms are taught together.
