Etymology
Origin of sparrow
First recorded before 900; Middle English sparowe, Old English spearwa; cognate with Gothic sparwa, Old Norse spǫrr
Explanation
A sparrow is a small brown bird. Sparrows live near humans and have a pretty, musical song. A sparrow is a different bird in the US than it is in other parts of the world. A "true sparrow" is found mainly in Europe, where it commonly nests in the eaves of buildings and in trees in cities. American sparrows got their name because they resemble true sparrows at first glance — they're both small, round, brownish birds — but they're from completely different families.
