Etymology: "Subtest" is a plain compound: the prefix "sub-", meaning "under" or "subordinate to", from Latin "sub", attached to "test". Together they name a smaller examination that forms one part of a larger assessment, such as a single section of a battery of psychological tests or one component of a multi-part exam. The "test" half comes from Old French "test", a cup or pot used to refine metals, and ultimately from Latin "testum", an earthen vessel. Its sense of trial or examination grew out of that metallurgical process, since gold or silver was heated in such a vessel to see what was left behind. The prefix does the work of narrowing the focus: a subtest is a test within a test, a piece of the whole that can be judged on its own.

Synonyms: section, part, component, segment, subset
