Why is the language difference between North Korea and South Korea so great?

Although North Korea and South Korea both use the same language, the 70-year history of division on the Korean Peninsula has resulted in increasing language differentiation on both sides of national boundaries, which may sometimes lead to misunderstandings, hurt each other's feelings and sometimes make jokes. Some experts say that there are 1/3 differences in daily expressions between the two countries.

Because most words and grammar are still the same, both Korea and China can understand each other's language, but one of the two countries has become an international economic power and the other has chosen to close the door. The differences caused by external influences on languages are directly reflected in the languages of North Korea and South Korea.

Linguists say it takes two years for defectors to adapt to Korean. Because the political and economic systems of the two countries are completely different, even the same emotional words need time to adapt to their meanings and connections.
