In all his plays Shakespeare uses the Vergilian figure hendiadys some three hundred times, most frequently in his middle plays and most of all in Hamlet. Rare in English speech or other English poetry, hendiadys joins nouns, or sometimes adjectives, in a false or specious union (e.g., “sound and fury” for “furious sound”). Its effect in Hamlet, where it appears perhaps sixty-six times, is often to elevate, estrange, and baffle; and this stylistic use of conjoined terms that are neither parallel nor complementary mirrors the play's deepest themes—especially the suspect character of personal unions and metaphysical connections. Once aware that Shakespeare frequently combines terms this way, we can understand better many puzzling phrases, including some celebrated ones. Three appendixes list instances of hendiadys in Hamlet, tabulate its incidence in all the plays, and discuss some misleading definitions in the OED.
