Origin of building

First recorded in 1250–1300, building is from the Middle English word byldinge. See build, -ing 1

Explanation

Building is the process of making something. Building Lego cities and towns is the favorite activity of many kids. When a construction company is building a structure like a grocery store or a school, you can say it's building a building. Anything from a small house to a skyscraper can be called a building, and both meanings of the word come from the verb build, with its Old English root byldan, "build or construct a house."
