Most one can merely guess at. Parataxis? A new form of military transport. Pleonasm? A heresy prevalent in Greece in the 4th and 5th centuries BC. Aporia? A small town in upstate Michigan, used by market researchers to test out new lines ("let's see how it plays in Aporia"). Zeugma? A dogma stubbornly adhered to by believers in Zeus. Scesis onomaton? Haven't a clue. Dirimens copulatio? We won't go into that, if you don't mind. Synecdoche, though, is easy. It's a newly discovered opera by Handel, staged in London last week with a cast all dressed as reindeer, to mixed reviews.
