Etymology

Dy stands for the element dysprosium, and its name comes from the Greek word dysprositos, which means 'hard to get' and whose part dys- means 'difficult' (as in 'dyslexia'). Scientists gave it this name because it is a rare metal that was hard to separate from others, so remember Dy as a 'hard to get' rare earth often used in strong magnets and lasers.
