suppositionally

Suppositionally is an adverb meaning in a hypothetical or assumed way. It introduces a condition or possibility so that the consequences can be considered without asserting that the condition is true: for example, a planner might say, “Suppositionally, demand doubles next year.” Its use is relatively formal and specialized, especially in legal, academic, and analytical discussion, but it is fully understandable in ordinary contexts. The word is more precise than “maybe,” because it marks an explicit hypothetical frame rather than expressing simple uncertainty, and more emphatic than “perhaps,” because it signals a developed assumption. It is also distinct from “supposedly,” which reports what someone claims rather than creating a conditional scenario. Suppositionally is therefore especially useful when testing a plan, exploring a counterfactual, or explaining what would follow from a stated premise.

In a hypothetical or assumed way; as a supposition.

Where does suppositionally come from?

The word is formed from the noun “supposition” plus the adverbial suffix “-ally.” “Supposition” comes from Latin suppositio, a placing or setting under, developed in Latin and French into the sense of an assumption or supposition. Related English words include “suppose” and “suppositional,” while “composition” ultimately shares the Latin root through the family of Latin words formed with posponere or componere.
