Strangely enough, dysprosium isn't an annoying tendency to burst into very bad verse, but a chemical element.
Word Not To Use Today: dysprosium. This word comes from the Greek dusprositos, difficult to get near, with -ium added on to make it look more like the name of an element.
Dysprosium is a metal, Atomic Number 66, symbol Dy. It's used in lasers and nuclear control rods.
