The word "potency" originates from the Latin potentia, meaning "power" or "ability," derived from potens (powerful). The root poten- reflects strength or capability, while the suffix -cy (from Latin -tia) forms abstract nouns indicating a state or condition. Over time, "potency" evolved in English to describe both physical and metaphorical strength, particularly in medicine (e.g., drug potency) and general contexts (e.g., leadership potency).
