The adjective is derived from Late Middle English potable (“drinkable, potable”),[1] from Middle French, Old French potable (modern French potable (“drinkable, potable”)), and from its etymon Late Latin pōtābilis (“drinkable, potable”), from Latin pōtāre (“to drink”) + -bilis (suffix forming adjectives indicating a capacity または worth of being acted upon).[2] Pōtāre is the present active infinitive of pōtō (“to drink”), from Proto-Italic *pōtos, from Proto-Indo-European *peh₃- (“to drink”).
The English word is cognate with Catalan potable, Italian potabile, Spanish potable.[2]
