Usage
Where does ostrich come from? A funny-looking animal with a funny origin story is the ostrich. When you look at an ostrich, with its small head, big, long legs, and large, fluffy body, the first thing you think of is a tiny, adorable sparrow, right? Wait, what?As it happens, that's what the ancient Greeks thought, apparently. The word ostrich ultimately comes from the Greek word strouthion, which comes from the Greek expression for "big sparrow." That's right, it seems the Greeks thought the ostrich was just a really big, weird sparrow. Funnily enough, the ancient Greeks also called the ostrich strouthokamelos, which means "camel-sparrow," because the bird has a long neck like a camel. The roots of these other words may get a rise—of laughter or surprise—out of you. Run on over to our roundup of them at "Weird Word Origins That Will Make Your Family Laugh."

Etymology
Origin of ostrich
First recorded in 1175–1225; Middle English ostrice, ostriche, from Old French ostrusce (compare French autruche, ) from unattested Vulgar Latin avistrūthius, for Latin avis “bird” + Late Latin strūthiō, from Late Greek strouthíōn; see struthious
Explanation
An ostrich is a huge, flightless bird with long legs and two toes on each foot. Although they weigh as much as 265 pounds, ostriches can run almost 45 miles per hour. Ostriches are related to emus, but they're about three times larger. There are two modern species of ostrich, both native to Africa. Ostriches are often farmed for their distinctive soft, loose feathers (which are used in feather dusters and in fashion design). Colloquially, an ostrich is also someone who avoids difficulty by refusing to face it, a use that comes from the birds' habit of putting their heads in the sand — although they do it to hunt for snacks!
