It is the hypothetical source of/evidence for its existence is provided by: Sanskrit pati "drinks," panam "beverage;" Greek pinein "to drink," poton "that which one drinks," potos "drinking bout;" Latin potare "to drink," potio "a potion, a drinking," also "poisonous draught, magic potion;" Old Church Slavonic piti "to drink," pivo "beverage."

word-forming element in nouns of act, process, function, condition, from Old French and French -age, from Late Latin -aticum "belonging to, related to," originally neuter adjectival suffix, from PIE *-at- (source of Latin -atus, past participle suffix of verbs of the first conjugation) + *-(i)ko-, secondary suffix forming adjectives (see -ic).

early 15c., collective noun of quails and ladies, from Anglo-French bevée, which is of unknown origin. One supposed definition of the word is "a drinking bout," but this perhaps is a misprint of bever (see beverage). If not, perhaps the original sense is birds gathered at a puddle or pool for drinking or bathing. But the quest for a clear and logical origin in such a word might be futile. "These old names for companies of men and animals are however very fantastical and far-fetched" [OED].
