the word superimpose is a modern english formation, directly combining the latin prefix 'super-' with the verb 'impose'. 'super-' derives from the latin preposition meaning "over, above," which itself traces back to the proto-indo-european root uper, also signifying "over." the verb 'impose' entered english from old french 'imposer,' which originated from latin 'imponere,' a compound of 'in-' (on, upon) and 'ponere' (to place). the literal sense of "to place upon" from the latin components evolved logically into the modern technical and figurative meanings of laying one thing over another, whether physically as in images, or abstractly as in applying ideas.

Structure: super (over, above) + impose (place, set) super (latin origin, meaning "over, above", functions as a prefix indicating position or degree); impose (latin origin, from 'imponere' meaning "to place upon", functions as the core verb root).
