Usage Note
Common Mistakes
Using ふんふん to your boss or in formal business situations.
This is very impolite. Use "はい" (hai) to show you are listening in formal settings.
Confusing it with "フン！" (hun!).
A single strong "フン！" expresses disgust, snobbery, or dismissal. It must be repeated as ふんふん to mean listening or sniffing neutrally.
