The Latin word pes, meaning foot, and its form pedis give us the root ped. A pedestrian is a person who travels on foot. Before trains, planes, and cars, an expedition, or journey, was often carried out by foot. An impediment makes movement or progress difficult, as if getting in the way of the feet.
