In Korean grammar, demonstrative pronouns play an essential role in forming sentences. These pronouns help to point out or indicate specific objects, people, or places. In Korean, there are three significant demonstrative pronouns: 이 (this, for close objects), 그 (that, for objects at a medium distance), and 저 (that, for objects far away). By mastering the use of these pronouns, you will be able to express yourself more accurately and communicate better with native speakers.
