The best thing about congeries is that it’s a singular noun. Otherwise I’d use the word “list.” List means exactly the same thing, but it has none of the exoticism of congeries, no spice, no adventure, no derring-do, no whiff of the palm tree and the jungle, no pizzazz, no fairy-dust, no magic. Also everybody knows how to pronounce “list,” but no two dictionaries can agree on congeries, which makes it much more fun. The plural, incidentally, is congeries.
