Building, edifice, structure refer to something built. Building and structure may apply to either a finished or an unfinished product of construction, and carry no implications as to size or condition. Edifice is a more formal word and narrower in application, referring to a completed structure, and usually a large and imposing one. Building generally connotes a useful purpose (houses, schools, business offices, etc.); structure suggests the planning and constructive process.

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."
