Latest News About Arch Definition

Here’s the latest publicly available overview on arch definitions.

• In architecture, an arch is a curved structure spanning an opening and transferring weight to supports, commonly used to bear loads above doors, windows, or passageways. Britannica’s dictionary similarly defines an arch as a curved structural element over an opening that supports weight. Cambridge defines it as a structure with a curved top on two supports that carries weight above the opening.[1][3][5]

• In human anatomy, the term arch refers to the raised curved area on the bottom of the foot formed by bones, with several arch types described in medical and anatomy references.[1]

• Recent general interest definitions emphasize the curved shape and structural function, including examples of arches in Roman architecture and modern masonry. Dictionaries in 2026 continue to describe the shared concept of a curved form that spans an opening or space.[2][4][5]
