"저" is a Korean pronoun that translates to "I" or "me" in English. It is used in formal or polite contexts, making it suitable for conversations with strangers, elders, or in professional settings. The use of "저" reflects the speaker's respect towards the listener. In contrast to informal pronouns like "나," which is used among friends or peers, "저" helps maintain a level of politeness. Understanding when to use "저" is essential for effective communication in Korean culture, where respect and hierarchy play significant roles in social interactions.
