What does 님 mean?
님 (nim) means: honorific after a name or title.
More respectful than 씨. It is how shops, hospitals and websites address customers (고객님, 박유민 님) and it is built into titles such as 선생님 (teacher) and 사장님 (boss). Calling someone by name + 님, or by a title, is how Koreans say 'you' politely without a pronoun.
