How to say "whistle" in Japanese
Choosing the right word
- 口笛くちぶえnounThe sound made with the lips: a person whistling a tune or signalling to someone. It is not a word for a whistle as an object.
- nounThe loanword, typically for a whistle as a device, such as a referee's, and for the sharp sound it makes; not for whistling with your lips.
- 警笛けいてきnounA warning signal: it covers horns, alarms and foghorns, and as a whistle it is a warning whistle such as a train's, not the sound you make with your lips.
- 笛ふえnounA general word for blown instruments — flutes and whistles alike. In the whistle sense it means the device itself, such as a referee's whistle, not the sound made with the lips.
Use 口笛 for whistling with your lips, 「ホイッスル」 for a whistle device such as a referee's, 警笛 for warning horns and whistles, and 笛 for a whistle or flute as an instrument.
