농담입니다 [ nongdam – imnida ]
농담 means ‘joke’ in Korean and 입니다 is a polite form of 이다 [ ida ], which acts like the verb ‘be’ in many sentences.
Let’s say you wanted someone to laugh at something you said that you think is funny. But sometimes the person feels awkward or even offended; or maybe they just don’t understand what you mean. In such cases, you can say 농담입니다, meaning ‘it is a joke’.
