What does "hippopotamus" mean and in what langauge?

The term "hippopotamus" originates from the Greek language, where "hippos" means horse and "potamos" means river. As such, "hippopotamus" literally translates to "River Horse" in English. This name is attributed to this large, semi-aquatic mammal due to its appearance, with a barrel-shaped body and a long, horse-like face. Despite its name, a hippopotamus is not related to horses or any other land-dwelling animals, but it is known for its habitat near rivers and water bodies, which suits its semi-aquatic lifestyle.
