‘Yes’ and ‘no’ are extraordinary because they have paralinguistic and extralinguistic equivalents: in addition to verbal yes and no, we have vocalised uh huh and uh-uh, and the gestures of nodding and shaking our heads. The trimodality — language, vocalisation and gesture — of ‘yes’ and ‘no’ is quite exceptional, making them a potentially significant area of research in understanding the origins of human communication.
I’d like to know how you communicate “yes” and “no” in your language and culture. How do you say “yes” and “no”? How do you vocalise “yes” and “no”? And how do you gesture “yes” and “no”?
