Korean pronouns are words used to refer to people or things without naming them directly. They can indicate the speaker, the listener, or others. Common pronouns include 나 (na) for "I," 너 (neo) for "you," and 그 (geu) for "he." Pronouns in Korean can change based on the level of formality and the relationship between speakers. In addition to personal pronouns, Korean also uses demonstrative pronouns like 이 (i) for "this" and 저 (jeo) for "that." Pronouns can also reflect respect, with 당신 (dangsin) being a formal way to say "you." Understanding these pronouns is essential for effective communication in Korean.
