< Greek: combining form of híppos; cognate with Latin equus, Old Irish ech, Old English eoh, Sanskrit aśvas, Lithuanian ašvà

Explanation

A hippo is a very large African mammal that lives both in and out of the water. Adult hippos can weigh well over 3,000 pounds. Hippos are the third-largest land mammals (after elephants and rhinos), and of the three, they are by far the most aggressive and territorial. These gray, hairless, barrel-shaped animals resemble enormous pigs, but they're more closely related to whales and dolphins. Hippo is shorthand for hippopotamus, a word that derives from the Greek ho hippos potamios, "the horse of the river."

Example Sentences

The prefix hippo- comes from the Greek word for "horse".
