coup de théâtre

Noun

coup de théâtre (plural coups de théâtre)

   • This may be due to the fact that Aeschylus, in the last play of the Oresteia (458 B.C.), brings him to Athens to stand trial for his mother's murder--a coup de théâtre that would have been spoiled if he had come from there in the first place.1996, Bernard Knox, endnotes to Robert Fagles's translation of The Odyssey

   Synonyms:

   twist

2. A theatrical trick or gesture, something staged for dramatic effect.
   • I had arranged to track her husband down, reason with him, work on his feelings, telegraph for his wife, and in an affecting interview throw them into each other's arms.
