Aizuchi
In the Japanese language, aizuchi are interjections during a conversation that indicate the listener is paying attention or understands the speaker. In linguistic terms, these are a form of phatic expression. Aizuchi are considered reassuring to the speaker, indicating that the listener is active and involved in the discussion.
Examples
Common aizuchi include:- ,, or
- ,,, or
- nodding These have a similar function to English "yeah", "yup", "OK", "really?", "uh-huh", "oh", and so on.
Aizuchi can also take the form of so-called echo questions, which consist of a noun plus. After Speaker A asks a question, Speaker B may repeat a key noun followed by desu ka to confirm what Speaker A was talking about or simply to keep communication open while Speaker B thinks of an answer. A rough English analog would be "A..., you say?", as in: "So I bought this new car"; reply: "A car, you say?".
