The story of the word

Two unrelated Greek words collide in English here. Soil pedology comes from πέδον, ground, while the pedology that means the study of children comes from παῖς, παιδός, child, and pedal comes from Latin pes, foot. Soil scientists increasingly say pedology only in print and dig their trenches without arguing about it. The discipline itself was built by Vasily Dokuchaev in Russia in the 1880s, who showed that soil is a body with a history rather than crushed rock.
