Among the most heinous linguistic developments of the 21st Century has to be the semantic transformation of the word bubble. Children revel in all types of bubbles. There are ones made of snot, most useful for preteens when they want to gross-out a friend. Native to middle school lockers, there are bubbles made from Bazooka gum, which migrate every spring to Little League dugouts. Then of course, there is my favorite: Willy Wonka’s Chewing Gum bubble. Violet’s shade of purple provided the color to much of my childhood.
