Etymology: "Superimposes" is the third-person singular of "superimpose," a verb built from the Latin prefix "super-" ("over, above") and "imponere," meaning "to place upon," itself from "in-" and "ponere" ("to put, place"). The English verb arrived in the early 1600s, and its earliest senses were literal: to lay one thing on top of another physically. That concrete image of one object set atop a surface is still the core of the word. The modern sense of layering images came later. Photographers in the 19th century used "superimposition" to describe exposing one image over another on the same plate to produce a double exposure, and film and then television adopted the term for on-screen text and graphics. The verb's extension into digital design and interface work followed the same logic, so the meaning of placing one thing over another has stayed remarkably consistent for four centuries, even as the materials have changed from ink and glass to pixels.
