1. A figure of speech in which two words connected by a conjunction "and" are used for emphasis to express a single notion that would normally be expressed by an adjective and a noun or expressed by two nouns or two adjectives joined, rather than by an adjective-noun combination: Examples of hendiadys include the following: "grace and favor" instead of "gracious favor"; "nice and warm" instead of "nicely warm"; "sound and fury" instead of "furious sound"; or as Virgil wrote, "We drink from cups and gold" instead of "golden cups".
2. Etymology: from Greek and Latin hen dia duoin, "one by means of two" or "one by two."
