"어떤" (eotteon) is a Korean word that translates to "what" in English. It is used to inquire about the nature or type of something. For example, when asking "어떤 책을 읽고 있어요?" (What book are you reading?), it seeks specific information about the book in question. In addition to its interrogative use, "어떤" can also describe a particular quality or characteristic. For instance, "어떤 사람" (what kind of person) refers to the traits or attributes of an individual. This versatility makes "어떤" an essential word in everyday conversations in the Korean language.
