Research Point: Form and Shape

Trouble with language. The course explains that we must not confuse the term form and shape. Form is 3D whereas shape is flat. I have to accept that this is the common language used in the art world, but I have trouble understanding it. I wrote in my earlier post about Barbara Hepworth’s shapes and that word sounds perfect to me; on the other hand I would not describe the body as a shape. Perhaps my logic is not perfect either. I looked for the origin of the words.

Form is from the Latin forma – derived from Greek morphe

Shape is from Old English gesceap: a creation

How can something that has morphed from something else be more 3D than a creation?
