In this episode of Wise Up!, Emma and Katherine explore the tiny words and sounds we use every day, like “ow,” “ouch,” “um,” “ew,” “wow,” and “oops.” Why do we say “ow” when something hurts? Why does “um” pop out when we are thinking? Are these real words, or just random sounds?

Join us as we discover how these little expressions help our brains, bodies, and conversations. From pain signals to brain “loading screens,” this episode shows that even the smallest words can have big meanings.
