What does hypothetical mean?
The adjective hypothetical describes something that is possible in theory, imagined, or dependent on an assumption rather than known facts. It is commonly used in academic, legal, scientific, and public-policy discussions when examining possible circumstances, consequences, or examples. For instance, a researcher might discuss the hypothetical effects of a new regulation, or a teacher might construct a hypothetical situation to encourage analysis. Although hypothetical things are not necessarily believed to be real, the word can suggest that a scenario is being considered seriously, even when it is unlikely. In formal writing, it provides a concise way to distinguish a conditional or speculative idea from an established fact. The related noun hypothesis usually refers to a proposed explanation or prediction that may be tested, while hypothetical more often modifies a situation, case, or example.

Where does hypothetical come from?
The word comes from the Greek hypothetikos, meaning “pertaining to a hypothesis” or “conditional.” Its ultimate roots combine hypo-, meaning “under,” with thesis, meaning “placing” or “setting down,” reflecting the idea of a proposition set down as a supposition. The English form developed through Latin and French, and cognates such as hypothesis and thesis preserve the same Greek foundation.
