cross-case

The compound adjective "cross-case" is a modern formation, primarily emerging from technical and analytical fields like computer science, statistics, and social research. Its first element, "cross," derives from the Latin 'crux', which originally denoted a physical stake or structure but evolved to signify intersection or traversal. The second element, "case," originates from the Latin 'casus', meaning a fall or an event, which broadened to signify a specific instance or set of circumstances. When combined, the literal sense of "across instances" logically yields the modern technical meaning of analysis or comparison that spans multiple distinct situations, datasets, or examples.

Structure: cross (across) + case (instance/situation) - cross: From Old English 'cros', from Old Norse 'kross', from Old Irish 'cros', from Latin 'crux, crucis' (stake, cross). Functions as a combining form meaning "across," "transverse," or "intersecting." - case: From Old French 'cas', from Latin 'casus' (a falling, an occurrence, chance), from the verb 'cadere' (to fall). Functions as a noun meaning "an instance," "a particular situation or occurrence," or "a container."
