Twice a day the River Thames recedes, revealing a muddy shoreline. Hobbyists known as mudlarks stroll the surface searching for objects that have found their way into the river over the centuries, everything from ancient Roman jewelry to modern wedding rings. A new book about mudlarking describes the irresistible appeal of searching for treasures and the stories behind them. Also, why do performers whisper the phrase toi, toi, toi to wish each other well backstage before a show? And, what’s the plural of octopus? Octopuses? Octopi? Something else? Plus, schniddles vs. schnibbles, visiting vs. talking, fotched a heave, creature comforts, trade-last, a timely pangram, Doves Type, a brain teaser about malapropisms, and more.
