The study showed a significant subpotency in the medication after it was stored improperly.
Subpotency → It is formed from "sub-" (meaning under) and "potentia" (from Latin, meaning power or ability). The word refers to a state of having less power or ability than something else, indicating a lower level of potency.
Think of being 'under' ('sub-') a certain 'power' ('potentia') — this helps you remember that subpotency means having less power.
