Structure

In science, structure is a fundamental concept. It means the arrangement of parts. Examples are the organs in a body, or  crystals in a substance like granite. 

A structure may refer to buildings, machines and similar things made by people as well as to a rock or a mineral, atoms or sentences. It always reflects the hierarchy of its parts.
