Korean expressions are phrases or sayings used in the Korean language that convey specific meanings or emotions. They often reflect cultural values and social norms, making them an essential part of communication in Korea. Many expressions can be idiomatic, meaning their meanings are not directly derived from the individual words used. These expressions can vary in formality, with some being suitable for casual conversations and others reserved for formal situations. Learning these expressions can enhance understanding of Korean culture and improve language skills, as they often encapsulate unique concepts and feelings that may not have direct translations in other languages.
