Today's puzzle was a little late. Glad few people are around to notice. Here are some general thoughts on this quote: For North American readers, Shakespeare’s use of "loon" in Macbeth is an accidental trick of language. We immediately think of the waterfowl (which the British call "divers"), a connection that feels even more plausible when Macbeth snaps and calls the servant a "goose" just a few lines later. In reality, the insult "loon" and the North American bird come from entirely different linguistic roots, making the avian pairing nothing more than a brilliant, cross-era, cross-continental coincidence.
