Etymology

The word "subtest" combines the Latin prefix "sub-" (meaning "under" or "secondary") with the noun "test" (from Latin testum, originally referring to an earthen pot but later evolving to mean "trial" or "examination"). The term emerged in the 20th century within psychological and educational testing contexts, logically describing a smaller test nested within a broader assessment battery. The prefix "sub-" maintains its classical sense of hierarchy, while "test" retains its modern evaluative meaning.
