Speakers use pointing gestures for many discursive functions. This project analyzes pointing gestures made by five people during a dinner conversation. I describe functions discussed in previous studies and note them in these data. I also identify an additional purpose: pointing at the last speaker to indicate agreement with his or her statement. This project adds to the growing body of research on pointing gestures and has implications for professionals in myriad of fields. I mention the specific application to sign (...) language interpreters, who may miss vital non-verbal cues when unable to see the speaker for whom they interpret. (shrink)
