Etymology Origin:
The word "potable" traces back to Latin potabilis, derived from potare (to drink). The suffix -able was added to form an adjective meaning "capable of being drunk." Over time, it entered Middle English via Old French, retaining its core meaning of "safe to drink." The logic is straightforward: pot (drink) + able (capable) = "drinkable."
