What does superposing mean?
Superposing means placing one thing over another so that the two coincide, partly overlap, or are evaluated in the same position. The term is especially common in mathematics and physics, where shapes, vectors, signals, or physical systems may be superposed for comparison or combined under specific rules. It also has a practical use in computing and image editing: one image or graphic can be laid over another while both remain visible or accessible. Superposing is closely related in meaning to superimposing and overlaying, but it often carries a more technical or precise tone. The expression can describe both a physical arrangement and a mathematical operation, depending on context. It is useful whenever the relationship between two layers or configurations is important rather than merely the presence of either one alone.
verbTo place one thing over another so that the positions or outlines of the two correspond, partly overlap, or coincide. It is used especially in geometry, physics, computing, and image editing.
- To place one object, image, or figure over another so that they overlap or correspond.
- To combine mathematical or physical entities by placing them in the same position or configuration.
"The technician carefully avoided superposing the labels when aligning the two diagrams."
"Superposing the original photograph over the scan revealed where the colors had faded."
"The diagram is produced by superposing two geometric figures with a common baseline."
Superposing is what lets two images occupy the same space while remaining independently visible.

Etymology of superposing
The word comes through French superposer from Latin superponere, a compound of super-, meaning “over,” and ponere, meaning “to place.” English usage developed in mathematical and scientific contexts, particularly for the placement of geometrical figures or the combination of physical states. Later uses extended the same underlying idea to transparent images, graphics, maps, and other visual layers.

How superposing is actually used
This is chiefly a technical or formal word, especially in mathematics, physics, computing, cartography, and image processing. In general English, “superimpose” is often more natural.
