rhinoceros

noun

rhi·​noc·​er·​os rī-ˈnäs-(ə-)rəs 

plural rhinoceroses also rhinoceros

: any of various large plant-eating mammals of Africa and Asia that are related to the horse and have a thick skin with little hair, three toes on each foot, and one or two heavy upright horns on the snout

Etymology

Middle English rinoceros "rhinoceros," from Latin rhinocerot-, rhinoceros (same meaning), from Greek rhinokerōt-, rhinokerōs, literally "nose-horned," from rhin-, rhis "nose" and keras "horn"

Word Origin

One of the largest animals found on land today is the thick-skinned rhinoceros. Another of the animal's characteristics, besides large size, is found on its snout. All rhinoceroses have at least one horn, and some have two horns. The English name for this animal with a horn or horns on its snout was borrowed from Latin rhinoceros. The Latin name, in turn, came from the Greek word rhinokerōs, which literally means "nose-horned." This word is made up of the Greek word rhin-, rhis, meaning "nose" and the word keras, meaning "horn."
