Without any drinks or lacking the ability to drink; not containing or serving beverages.
From English 'drink' (from Old English 'drincan') + suffix '-less' (meaning 'without'), creating an adjective meaning the absence of drink.
This word is surprisingly rare in everyday use, but it perfectly demonstrates how English's '-less' suffix can be attached to almost any noun to express absence—a wildly productive feature that lets speakers create new words on the fly.
