# Form

Form is the shape, visual appearance, constitution or configuration of an object. In a wider sense, the form is the way something is or happens, the answer to "how?". When then considering the idea of global form, the sense of form reaches the one of Gestalt, as in Gestalt psychology.

Form may also refer to the following:
