What does form follows function mostly nearly mean?

"Form follows function" is a design principle that suggests the shape of a building or object should primarily relate to its intended purpose or function. This concept emphasizes that the design should be guided by the utility and practicality of the object rather than aesthetic considerations alone. It originated in architecture and industrial design, promoting efficiency and simplicity in design. Ultimately, it advocates for a harmonious relationship between an object's appearance and its intended use.
