Etymology

Calomel comes from old Greek parts kalo- meaning 'beautiful' and -mel meaning 'black', a name people gave because a dark form appeared when the substance was made long ago. So, the word stuck to this old medical powder that actually contains mercury, and that link helps you remember it as an old medicine rather than a modern drug.
