What does superimpose mean?
Superimpose means to place one thing over another. The upper item may partly or completely cover the lower one, although in design and image editing it often remains visible as an additional layer. The word is especially common when discussing photographs, diagrams, maps, typography, logos, and technical drawings. For example, a caption may be superimposed over a video, or one transparency may be superimposed on another to produce a composite image. Although the action described is simple, superimpose has a formal, professional tone and suggests deliberate arrangement rather than an accidental overlap. It is also used more broadly for adding one system, pattern, or set of information over another. In everyday discussion, overlay is often the clearer and more conversational alternative.

Where does superimpose come from?
Superimpose was formed in English by combining the Latin-derived prefix super-, meaning “over” or “beyond,” with impose. The verb impose comes through French from Latin imponere, from in- and ponere, meaning “to place upon.” The resulting word preserves the basic sense of placing one thing upon or over another.
