I love etymology. Whether it’s shattering the dreams of a co-worker who named his baby “mark” in the hope his son would leave the same on the world (the name is from the latin Marcius, from Mars, the God of War) or puzzling out the mysterious “mommixity” (possibly from French mommuck, to annoy) from Birds Without Wings, I dig them words.
Here’s a recent book for fans of the weird word, The Dord, The Diglot and an Avocado or Two, by Anu Garg. (Hat tip to Boing Boing.)
