Korean phrases are essential expressions used in the Korean language to communicate effectively. They can range from simple greetings like "안녕하세요" (annyeonghaseyo), meaning "hello," to more complex sentences used in daily conversations. Learning these phrases helps in understanding Korean culture and enhances interactions with native speakers. Many Korean phrases are rooted in honorifics, reflecting the importance of respect in social interactions. For example, using "선생님" (seonsaengnim) to address a teacher shows politeness. Mastering these phrases can significantly improve language skills and foster connections with Korean speakers.
