Form, figure, outline, shape refer to an appearance that can be recognized. Form, figure, and shape are often used to mean an area defined by contour without regard to other identifying qualities, as color or material. Outline refers to the line that delimits a form, figure, or shape: the outline of a hill. Form often includes a sense of mass or volume: a solid form. Shape may refer to an outline or a form: an “S” shape; a woman's shape. Figure often refers to a form or shape determined by its outline: the figure eight. Form and shape may also be applied to abstractions: the shape or form of the future. Form is applied to physical objects, mental images, methods of procedure, etc.; it is a more inclusive term than either shape or figure : the form of a cross, of a ceremony, of a poem.
First recorded in 1175–1225; Middle English forme, from Old French, from Latin forma “form, figure, model, mold, sort,” Medieval Latin: “seat”
From the Latin suffix -fōrmis
The way something (or someone) is shaped or arranged is its form. You might use it to describe the way a person looks walking in the woods at dusk by saying, "Her form was almost lost between the shadowy trees." Physical objects have a form, and so do less tangible things like music, movies, and stories. When form is used as a verb, it means "to give shape to," as when a filmmaker works to form the narrative of her movie so that it makes sense to the audience.
