Etymology

Origin of form¹

First recorded in 1175–1225; Middle English forme, from Old French, from Latin forma “form, figure, model, mold, sort,” Medieval Latin: “seat”

Origin of -form²

From the Latin suffix -fōrmis

Explanation

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.
