History for hippopotamus

The bulky African mammal that spends its daytime hours sunk up to its eyes in a river owes its English name to the ancient Greeks. The historian Herodotus called the animal, which he may have seen in Egypt, ho hippos ho potamios, “the river horse.” Later Greek writers reduced this description to hippopotamos (which looks as if it should mean “horse river”). Despite its name, the hippopotamus is more closely related to hogs than horses.
