science-fiction

The compound term "science-fiction" is a modern English formation, first used in the 1850s but popularized in the 20th century. It is a straightforward combination of "science," derived from the Latin scire (to know), representing systematic knowledge of the physical world, and "fiction," from the Latin fingere (to form or invent), representing imaginative creation. The term's logic lies in its literal meaning: "fiction based on science," where scientific principles, discoveries, or speculations provide the foundational logic for imaginative narratives. This genre distinguishes itself from pure fantasy by its attempt to ground its speculative elements in a framework of rational or extrapolated scientific thought, bridging the empirical and the imaginative.

Structure: science (knowledge) + fiction (invented story) - science: From Latin scientia (knowledge), from scire (to know). Functions as a noun modifier indicating the subject or basis. - fiction: From Latin fictionem (a fashioning, feigning), from fingere (to shape, form, devise, feign). Functions as the core noun, meaning a created narrative.
