Take the woodpecker, for example. Its Czech name is DATEL, which initially doesn’t seem that meaningful. But the original name was DLOUBATEL, based on the verb DLOUBAT, meaning “to peck.” So the name is pretty logical, referring to the bird pecking at trees. People just got lazy over time and shortened it to DATEL. If you want to impress your Czech friends, you can tell them about the origin of the woodpecker’s name.
